Query parameters: { This data will be updated every 24 hours. Field emission scanning electron microscopy (FESEM; Zeiss Supra55VP) was used to examine film morphology and estimate thickness. Rock-salt SnS has been mostly obtained by solution processing methods at low temperatures of less than 80 °C [Reference Garcia-Angelmo, Romano-Trujillo, Campos-Álvarez, Gomez-Daza, Nair and Nair19, Reference Chalapathi, Poornaprakash and Park20, Reference Breternitz, Gunder, Hempel, Binet, Ahmet and Schorr21]. Ca(F-amd)2 would be consumed much faster when the Ca cations replace the Sn cations than growing only one layer of CaS alone as in bulk CaS growth, which is consistent with the faster depletion of Ca precursor across the furnace at high temperature. Figure 3(a) shows that the alloy films deposited at all temperatures had higher Ca content than the additive model prediction, where the atomic ratio of Ca/(Ca + Sn) was calculated to be 0.12. 90767 CALCIUM SULFIDE, 99.9% pure, -325 mesh, CaS. October 14, 2020. this version. The tin can be used in amounts of from 10-5 to 10-1 gram-atom per gram-mole of calcium sulfide matrix, with the preferred tin concentration being about 5 × 10-3 gram-atom. On the other hand, annealed films deposited at 160 °C have resistivity of 100–300 Ω cm, which could be suitable as absorbers. As shown in Fig. Donsanti, Frédérique In hotter water that diminishes to 1/100th (0.01) of a single percent. Figure 7(b) shows the 2DXRD spectrum of an as-deposited and annealed film. A newly developed Ca precursor has significantly lowered the CaS ALD temperature window to 150–275 °C, which allows an overlap of the CaS and SnS ALD windows and, thereby, enabling (Sn,Ca)S alloy formation using layer-by-layer deposition of SnS and CaS [Reference Kim, Yang, Powers, Davis, Lou and Gordon35]. Sore Throat Warning: Severe or persistent sore throat for more than 2 days or if accompanied by high fever, headache, nausea, vomiting or rash may be serious. Calcium nitrate and sodium sulfide solutions react to form solid calcium sulfide and sodium nitrate solution. It would be 2 KBr + CaS == K2S + CaBr2. Labels, All Index Calcium sulfide and aluminium oxide inclusions in 51CrV4 spring steel Calcium-aluminate inclusions in UNS G92600 spring steel Carbonitride, nitride, sulfide and oxide inclusions in high-Cr ferritic stainless steels ... TiN+BN, MnS+BN inclusions in structural 20-KCX steel TiN+MnS, (NbmTi)(C,N), Al2O3+TiN inclusions in low-carbon microalloyed steel High-resolution X-ray diffraction (XRD) was performed on the alloy films, and the peak positions were compared with simulated diffraction peak positions of α-SnS, rs-SnS, π-SnS, and CaS to determine the crystal structure of the alloy films. Thus, despite the apparently high content of Ca, the cation replacement needs to only happen for less than 3/4 of topmost monolayer of SnS during the Ca(F-amd)2 dose to reach a Ca/(Ca + Sn) value of 0.62, which is not unreasonable. Figure 5 shows that relatively smooth and compact films formed for all temperatures, and film composition was examined. Molar mass of CaS = 72.143 g/mol. Although we operated in the overlapping ALD temperature windows of SnS and CaS as shown in previous studies [Reference Sinsermsuksakul, Heo, Noh, Hock and Gordon9, Reference Kim, Yang, Powers, Davis, Lou and Gordon35], rough and spiky films were obtained over a wide range of temperatures and film smoothness decreased with increasing temperature. To examine the cause, we investigated the growth mechanism of the (Sn,Ca)S ternary film using a quartz crystal microbalance (QCM), which measured the in situ mass changes of the growing film. View Labeling Archives, Place tablets under tongue at least 15 minutes before or 30 minutes after eating, brushing teeth, or drinking anything except water. The presence of the cubic π-phase is verified using the synchrotron-based 2DXRD. The assignment of peaks around 31° is less definitive because several peaks from different phases crowd into that region. Convert grams Calcium Sulfide to moles or moles Calcium Sulfide to grams. The large effective mass reduces carrier mobility and, thus, impedes the collection of photoexcited carriers in the direction perpendicular to the planes of the layered SnS [Reference Albers, Haas, Vink and Wasscher5, Reference Abrikosov, Bankina, Poretskaya, Shelimova and Skudnova6, Reference Vidal, Lany, d’Avezac, Zunger, Zakutayev, Francis and Tate7]. Figure S3 shows the plots of (αhν)n versus photon energy for the (Sn,Ca)S films of different compositions. A TEM analysis was carried out on a biphasic nucleus composed of a calcium sulfide (CaS) and a spinel (MgAl2O4), surrounded by a TiN particle. We can see in Fig. Calcium Sulfide CaSO4 Calcium Sulfate CBr4 Carbon Tetrabromide CCl2F2 Dichlorodifluoromethane CCl4 Carbon Tetrachloride Cd(NO3)2 Cadmium Nitrate CdS Cadmium Sulfide CF4 ... Tin(IV) Chloride SnF4 Stannic Fluoride SnO2 Tin Dioxide SO2 Sulfur Dioxide SO3 Sulfur Trioxide SO4 Sulfate Ion SOCl2 Thionyl Chloride Sr(NO3)2 Compositions of the inlet samples were used to avoid the complication of possible precursor depletion across the furnace. (c) Synchrotron-based 2DXRD integrated spectra of thicker film (∼600 nm) with Ca/(Ca + Sn) = 0.33. 1 Structures Expand this section. After removing the precipitates by filtering, calcium sulfide or barium sulfide is added to remove another heavy metal contaminant as sulfides. 5(d)]. DISCLAIMER: This homeopathic product has not been evaluated by the Food and Drug Administration for safety or efficacy. Due to inconsistencies between the drug labels on DailyMed and the pill images provided by RxImage, we no longer display the RxImage pill images associated with drug labels. In this study, we report ALD of rock-salt (Sn,Ca)S films with controllable composition at relatively low substrate temperatures. Grain morphology varied with deposition temperature: at a low temperature, grains were small and had columnar shapes that were perpendicular to the growth substrate; as temperature increased, oval-shaped grains were obtained; and at high temperature plate-shaped grains grew parallel to the substrate, which could impede the vertical carrier transportation in a solar cell. DailyMed will deliver this notification to your desktop, Web browser, or e-mail depending on the RSS Reader you select to use. An SEM image of a 500-nm thick alloy film deposited at 190 °C shows the layered film with plate-shaped grains more clearly [Fig. Tin monosulfide solar cells have attracted increasing attention as a potential low-cost and environmental friendly substitute for the commercial thin-film solar cells based on CdTe and CIGS [Reference Ramakrishna Reddy, Koteswara Reddy and Miles1, Reference Sinsermsuksakul, Hartman, Kim, Heo, Sun, Park, Chakraborty, Buonassisi and Gordon2, Reference Sinsermsuksakul, Sun, Lee, Park, Kim, Yang and Gordon3, Reference Jaramillo, Steinmann, Yang, Hartman, Chakraborty, Poindexter, Castillo, Gordon and Buonassisi4]. They can be easily detected by optical microscopy. *TIN SULPHIDE is alchemist's gold. Properties of calcium sulfide: Oldhamite. The cation exchange reaction between Ca(F-amd)2 precursors and underlaying SnS can be described as: Figure 4: (a) Mass changes as measured by QCM during (Sn,Ca)S deposition using SnS:CaS dose ratio of 15:1. Calcium sulfide react with nitric acid to produce calcium nitrate, sulfur, nitrogen dioxide and water. Files, All Mapping All peaks in the as-deposited film are from π-SnS, with the strongest peaks being (400), (222), (440), and (622). In the direct transition model, SnS has a direct band gap of 1.35 eV, which is close to previous experimental results [Reference Sinsermsuksakul41], and the band gap of alloy films is around 1.38 eV, with only a weak dependence of band gap on Ca content. Thus, the cubic phase can be obtained for films thick enough for solar cell absorbers. Similar replacement could also occur during the Sn(A-amd)2 pulse following the CaS ALD cycle. (b) Van der Pauw and Hall measurements of 600 nm of Sn0.67Ca0.33S deposited at 135 °C and after annealing at 400 °C in H2S environment for 1 and 2 h. The absorption coefficient (α) and the optical band gap (E g) of the alloy film were determined from the transmittance (T) and reflectance (R) measurements using a Hitachi UV–Vis–NIR spectrophotometer. Published online by Cambridge University Press:  Tin (Sn) Pellets Overview. However, the 50 nm-thick π-SnS films are too thin to be effective solar cell absorbers [Reference Baek, Pyeon, Song, Chung, Kim, Baek, Kim, Kang, Choi, Hwang, Han and Kim22, Reference Bilousov, Ren, Törndahl, Donzel-Gargand, Ericson, Platzer-Björkman, Edoff and Hägglund23]. Calcium forms intermetallic compounds with aluminum, silver, gold, copper, lithium, magnesium, lead, and tin. Rough and spiky films are obtained by using Sn and Ca precursors with different ligands, whereas compact and smooth films are obtained when the two metal sources share the same ligands. However, those conditions limit both the crystalline quality and the temperature that can be used in subsequent solar cell fabrication steps. ›› Calcium Sulfide molecular weight. The answer will appear below; Always use the upper case for the first character in the element name and the lower case for the second character. As calcium content increases in the as-deposited films, each set of doublet peaks starts to merge into a broader and weaker peak, respectively. Other articles where Calcium sulfide is discussed: crystal: Ionic bonds: …such as barium oxide (BaO), calcium sulfide (CaS), barium selenide (BaSe), or strontium oxide (SrO). Although both carrier concentration and hole mobility were increased upon annealing, they are still not ideal for solar cell absorbers. Figure 5: (a)–(c) Cross-section (top) and top-view (bottom) SEM of 100–200 nm of (Sn,Ca)S ternary films deposited by Sn(F-amd)2 and Ca(F-amd)2 at different temperatures using an SnS:CaS ALD cycle ratio of 15:1. All of these films used for optimal measurement had a thickness between 120 and 160 nm as measured in SEM. In case of overdose, seek medical help or contact a Poison Control Center immediately. "shouldUseHypothesis": true, All these restrictions forced to search for new and effective precipitants. (current). If pregnant or breast-feeding, ask a healthcare professional before use. The protein exists as the heavy chain of a heterodimer, covalently bound through di-sulfide bonds to one of several possible light chains. The growth substrate in QCM experiment is coated with gold, resulting to a different crystallographic orientation as compared with bulk SnS deposition on Mo or SiO2 substrates that were used for all our other depositions. The y-axis represents the percentage of Ca in the cation mix of Sn + Ca, and the bottom spectrum represents pure SnS. Furthermore, the SnS:CaS cycle ratio was varied from 35:1 to 5:1 at a fixed temperature of 212 °C to study the effect on composition. Using Sn and Ca precursors based on the same ligand enables deposition of dense and conformal films.

Hepar sulphuris calcareum (Calcium Sulfide) 12X, Helps loosen phlegm (mucus) and thins bronchial secretions, relieves bronchial congestion. Further work needs to be carried out to fully understand the impact of precursor choice on film properties. The crystallographic structure and lattice parameters of the α-SnS, rs-SnS, and π-SnS are shown in Fig. 2 Names and Identifiers Expand this section. Electrical and optical properties are also analyzed to demonstrate the possibility of using it as solar cell absorber materials. Alloying is a powerful method to control material properties such as band gap, electrical properties, and crystal lattice constant [Reference Ning, Dou and Yang24, Reference Lou, Zhou, Kim, Alghamdi, Gong, Feng, Wang, Ye and Gordon25, Reference Bakke, Tanskanen, Hägglund, Pakkanen and Bent26]. The pure SnS film demonstrates two sets of characteristic doublet peaks at around 27° and 31°, respectively. As-deposited thin films are annealed at 400 C for 1 h in H2S/N2 environment at a pressure of 4 torr. and the risks of emission of toxic hydrogen sulfide. "peerReview": true, These calcium sulfide are of Grade A quality and come in a liquid-like appearance. Decomposes in boiling water and strong acids. The quartz crystal was placed near the inlet of the precursors. Similar ion exchange processes have been observed in the atomic layer deposition of other metal sulfide systems [Reference Thimsen, Peng, Martinson, Pellin and Elam39]. The blue square represents experimentally observed value, and the black dot represents the calculated value under the ideal mixture assumption. Compositional and quartz crystal microbalance results indicate that part of the underlaying SnS film is replaced and/or removed during the CaS ALD cycle during the ternary film deposition, possibly via a temperature-dependent cation exchange mechanism. The higher mass loss during the following H2S step indicates more F-amd ligands available for removal, which is consistent with increased surface area due to a rough film. 5 Chemical Vendors. Furthermore, if a significant portion of the Sn in the previously deposited SnS was replaced by Ca, the crystal lattice would be disturbed and roughing of the film would not be unexpected. 4 Related Records Expand this section. Thus, we postulate that ternary film deposition in ALD benefits from selecting precursors of the same ligands. However, the thermodynamically stable phase of SnS (known as α-SnS) has two native properties that could limit its performance as a solar cell absorber. Alternatively, there are reports of π-SnS deposited by atomic layer deposition (ALD) at temperatures up to 200 °C, but the π phase only dominates in films less than 100 nm thick, which is not surprising given that π-SnS is thermodynamically less stable than α-SnS. Out of scope information includes radiopharmaceuticals, contrast media, herbals, homeopathics, and food. ECS-0335765. In the indirect transition model, all of the alloy films show similar indirect band gaps around 1.20–1.23 eV, which are 0.15 eV lower than direct band gaps. & Articles, All The difference in Ca atomic ratio is high at the inlet of the reactor and increases from 0.21 to 0.67 as temperature increases, indicating more effective Ca incorporation at high growth temperatures. ... and tin metal. S2, QCM measurement of multiple super cycles of SnS and CaS deposition shows that the first SnS cycle following the CaS cycle has moderately higher growth rate than the subsequent SnS cycles, which indicates that cation exchange of the lighter Ca by the heavier Sn likely has occurred, although to lesser degree, and the film is, thus, still Ca rich. The copper can be used in amounts of from 10-5 to 5 × 10-3 gram-atom per gram-mole of calcium sulfide matrix, with the preferred copper concentration being about 10-3 gram This observation is difficult to explain in the conventional ALD context nor by our proposed cation replacement hypothesis. However, the cubic phase is partially converted back into orthorhombic after annealing, and the α-SnS doublet peaks are recovered. Calcium sulfide, CaS, crystallizes in cubes like rock salt and occurs as oldhamite in nature. Ionic Compound Formula K sp. The (Sn,Ca)S alloy films were deposited in a custom-built hot-wall ALD reactor by alternating SnS and CaS cycles using the recipe [(SnS)m–(CaS)]n, where m and n were integers used to adjust the composition and thickness of the film, respectively. They have the same structure as sodium chloride, with each atom having six neighbours. Nitric acid - concentrated solution. 8(a) that the resistivity increases with increasing amount of Ca in the film. The crystal structure transforms from orthorhombic to cubic as the calcium content increases. The latter one is performed at the Stanford Synchrotron Radiation Lightsource (SSRL). This could be caused by phase separation into SnS and CaS at high temperature, which agrees with the thermodynamic argument by Vidal et al. To view supplementary material for this article, please visit https://doi.org/10.1557/jmr.2019.337. this mixture is mixed with nickel nitrate. The exposure time for all the amidinate precursors are set to be 1 s, and H2S was exposed 3 s in the reactor. CAS[20548-54-3] FLAMMABLE Second, the α-SnS has an indirect band gap of 1.1 eV and a direct band gap exceeding 1.3 eV, which tends to reduce the achievable open-circuit voltage by up to 0.2 eV [Reference Vidal, Lany, d’Avezac, Zunger, Zakutayev, Francis and Tate7, Reference Tritsaris, Malone and Kaxiras8, Reference Sinsermsuksakul, Heo, Noh, Hock and Gordon9, Reference Miles, Ogah, Zoppi and Forbes10]. Crystal structure of the films is characterized before and after a high-temperature annealing process. Solubility Product Constants near 25 °C. The encoded transporter plays a role in regulation of intracellular calcium levels and transports L-type amino acids. In the additive model, the growth rate of (Sn,Ca)S was assumed to be equal to the sum of the growth rates of binary SnS and CaS films when they are being deposited separately, which were measured to be 0.33 and 0.9 Å/cycle, respectively, within the present temperature window. Contents The substances are listed in alphabetical order. Given that XPS data showed 5× higher Ca content than prediction under this deposition condition, we suspect that significant amount of cation replacement of Sn by Ca might have happened during the Ca(F-amd)2 dose. Meanwhile, the substrate holder used to support quartz crystal has different geometry than that for bulk film deposition, which could lead to different gas transport kinetics that affect the QCM results. This cation replacement hypothesis could also qualitatively explain the increasing Ca content with temperature as the replacement is likely to be driven thermally and higher temperature could facilitate faster and more complete reaction. Files, Presentations "metrics": true, PubMed, Actual prices can vary and may be higher or lower, as determined by availability and market fluctuations. Because the mixing enthalpy is in the order of 100 meV, there should exist a miscibility gap under thermodynamic equilibrium conditions.

"crossMark": true, A thicker film (600 nm) with composition near the phase transition (33% Ca) was deposited at 135 °C and examined by the synchrotron-based 2DXRD, which has higher resolution and beam intensity and can, thus, reveal more details in its crystal structure. Events, Resistivities of the as-deposited films are decreased by 1–2 orders of magnitude by annealing, further verifying our hypothesis that (Sn,Ca)S is a metastable material that undergoes phase separation during heating.
