Actual prices can vary and may be higher or lower, as determined by availability and market fluctuations. "openAccess": "0", Electrical and optical properties are also analyzed to demonstrate the possibility of using it as solar cell absorber materials. Calcium sulfide is the chemical compound with the formula Ca S.This white material crystallizes in cubes like rock salt. The individual ALD processes for SnS [Reference Sinsermsuksakul, Sun, Lee, Park, Kim, Yang and Gordon3, Reference Sinsermsuksakul, Heo, Noh, Hock and Gordon9] and CaS [Reference Kim, Yang, Powers, Davis, Lou and Gordon35, Reference Yang38] have been published elsewhere. "subject": true, 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. 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. Solubility Product Constants near 25 °C. However, it is worth noting that the (200) and (111) rock-salt peaks coincide with the (222) and (400) π-phase peaks, so we cannot exclude the possibility that the rock-salt phase also exists.

CaCO3 + H2SO4 --> ??? White, decomposes upon melting. "hasAccess": "1", Calcium nitrate and sodium sulfide solutions react to form solid calcium sulfide and sodium nitrate solution. Both the spiky film morphology and the discrepancy between predicted and actual composition are difficult to explain by the conventional ALD model, where the layer-by layer-growth and self-saturated surface reaction should result in smooth and stoichiometric films. We deposit films of tin–calcium sulfide by atomic layer deposition (ALD) and demonstrate the metastability of this material. E g is determined using the equation (αhν)n = A(hν − E g ± E ph), where A is a constant, n is the transition probability (n = 2 for direct-allowed transition and n = 1/2 for indirect-allowed transition), and E ph is the phonon energy [Reference Ritter and Weiser40]. ALD allows precise control of film of stoichiometry, where one can easily engineer the film composition by controlling the dose ratio of different precursors [Reference Miikkulainen, Leskelä, Ritala and Puurunen30, Reference Johnson, Hultqvist and Bent31, Reference George32]. Children under 12 years of age: Consult a doctor. 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. 5(d)]. What is the ionic equation for the reaction of iron (II) sulfide with hydrogen … 2020. 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. ChEBI. This data will be updated every 24 hours. "lang": "en" (b) Comparison of mass change in one CaS ALD cycle in a bulk CaS film (blue) and in the alloy deposition (red). BRONCHIAL AND BREATHING AIDE- aconitum napellus, calcium sulfide, spongia officinalis skeleton, roasted, tin tablet, aconitum napellus, calcium sulfide, spongia officinalis skeleton, roasted, tin tablet, All Drug Figure 2 shows the composition and uniformity of the as-deposit ternary films estimated from X-ray photoelectron spectroscopy (XPS), as denoted by the atomic ratio of Ca/(Ca + Sn). Resistivities of films deposited at 135 and 160 °C were measured using the van der Pauw method. Calcium has a density of 1.54 g/cc, a melting point of 839°C, and a vapor pressure of 10-4 Torr at 459°C. If pregnant or breast-feeding, ask a healthcare professional before use. The flake and needle formation indicates high degree of anisotropic film growth, which could be a result of combining the orthorhombic SnS and rock-salt CaS growth, although this effect was not manifested in the individual binary film growth. Feature Flags: { 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. As a new Sn precursor was being developed using the same F-amd ligand as the Ca precursor, we deposited the (Sn,Ca)S film again with Sn(F-amd)2 and Ca(F-amd)2 as the cation precursors, in an attempt to improve the film quality. Updated Ask a doctor before use if you have a persisient or chronic cough that lasts, is chronic such as occurs with smoking, asthma, chronic bronchitis, or emplysema or is accompanied by excessive phlegm (mucus). Contents 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. In this structure, (Sn,Ca)S film was sandwiched between Mo growth substrate and sputtered ITO. 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.

PubMed, Given the SnS growth rate of 0.33 Å/cycle, it takes at least 12 cycles to grow one monolayer of SnS. 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.

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. Both phenomena could be explained by phase separation of the metastable alloy. Similar ion exchange processes have been observed in the atomic layer deposition of other metal sulfide systems [Reference Thimsen, Peng, Martinson, Pellin and Elam39]. (c) Synchrotron-based 2DXRD integrated spectra of thicker film (∼600 nm) with Ca/(Ca + Sn) = 0.33. View all Google Scholar citations 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. "metricsAbstractViews": false, The peaks corresponding to different crystal structures are labeled by different markers. Zooming into a smaller region, we can see that the three peaks between 31° and 33° have slight positive shifts compared to the reference peaks for pure SnS. We can see in Fig. The crystal structure transforms from orthorhombic to cubic as the calcium content increases. One probable explanation is that as Ca atoms are incorporated into the SnS film, they occupy the Sn vacancies (V Sn), which is the major source of p-type conductivity [Reference Albers, Haas, Vink and Wasscher5, Reference Abrikosov, Bankina, Poretskaya, Shelimova and Skudnova6, Reference Vidal, Lany, d’Avezac, Zunger, Zakutayev, Francis and Tate7]. "peerReview": true, Titanium Nitride (TiN) inclusions are commonly observed in a Maraging steel containing Nitrogen and Titanium and remelted in a VAR furnace. Instructions on balancing chemical equations: Enter an equation of a chemical reaction and click 'Balance'. Cycle numbers are chosen so that the film thickness is 100–200 nm. XRD spectra of annealed films indicate that the cubic (Sn,Ca)S alloy films are converted to orthorhombic, likely due to phase separation into the thermodynamically stable phase of SnS. The rough and spiky morphology renders the films formed by Ca(F-amd)2 and Sn(A-amd)2 unsuitable for solar cell applications. This research was supported in part by the Center for the Next Generation of Materials by Design, an Energy Frontier Research Center funded by the U.S. DOE, Office of Science. Stop use and ask a doctor if new symptons occur, symptoms worsen or do not get better within 7 days for adults or 5 days for children, fever worsens or lasts more than 3 days, cough lasts more than 7 days or occurs with a rash or persistent headache.These could be signs of a serious condition. Compositions of the inlet samples were used to avoid the complication of possible precursor depletion across the furnace. Cobalt will react because it is the only element above Ni in the activity series 6 … 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. They can be easily detected by optical microscopy. ›› Calcium Sulfide molecular weight. Crystal structure of the films is characterized before and after a high-temperature annealing process. Calcium forms intermetallic compounds with aluminum, silver, gold, copper, lithium, magnesium, lead, and tin. Oxygen can be combined with various cations to form a large number of ionically bonded solids. S1, and their respective diffraction peak positions are shown in Table S1. Helps loosen phlegm (mucus) and thins bronchial secretions, relieves bronchial congestion. Heating calcium with silicon, phosphorus, or graphite in the absence of air gives calcium silicides (Ca 2 Si, CaSi, and CaSi 2), calcium phosphide (Ca 3 P 2), and calcium carbide (CaC 2), respectively. Alternate cycles of SnS and CaS were deposited using Ca(F-amd)2 and Sn(F-amd)2, respectively, at different temperatures within the overlapping ALD temperature window from 135 to 190 °C and at different SnS:CaS cycle ratios. The assignment of peaks around 31° is less definitive because several peaks from different phases crowd into that region. DE-AC02-76SF00515. The direction of these shifts is surprising because standard tables of ionic radii suggest that calcium ions are larger than divalent tin ions. Labels, All Index Figure 4(b) compares the mass change of one CaS cycle inserted into a (Sn,Ca)S deposition and that in bulk CaS deposition. 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 performed using both high-resolution X-ray diffraction (HRXRD; Bruker D8) (Cu Kα radiation, λ = 1.542 Å) θ–2θ scans and synchrotron-based 2DXRD (λ = 0.9744 Å) at beamline 11–3. Figure 7(b) shows the 2DXRD spectrum of an as-deposited and annealed film. In this study, we report ALD of rock-salt (Sn,Ca)S films with controllable composition at relatively low substrate temperatures. As-deposited thin films are annealed at 400 C for 1 h in H2S/N2 environment at a pressure of 4 torr. A nucleus is observed next to a large number of TiN inclusions. 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. While orthorhombic SnS is energetically favorable, they demonstrated that the rock-salt phase (space group $fm3\bar{m}$) has a formation enthalpy only 0.08 eV above that of the orthorhombic phase. 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. Absorption spectra of the films were measured using a Hitachi U-4100 UV–Vis–NIR spectrophotometer. What is the ionic equation for the reaction of calcium carbonate with sulfuric acid? Films deposited at 160 °C have resistivities in the range of 102–104 Ω cm, but films deposited at 135 °C demonstrate much higher resistivities, possibly because of their smaller grain size and columnar-shaped grains which are aligned perpendicular to growth substrates. However, the delay itself is insufficient to explain the 5× higher Ca content, and more QCM data in fact showed no noticeable delay in SnS growth immediately after the CaS cycle. 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.

Over the 10-12,000 gallon lifetime of our shower filter cartridges, less than 6/100ths (0.06) of 1% will dissolve, but that is only in the coldest water (0ºC/32ºF). High-quality SnS and CaS thin films have been successfully deposited by ALD using various precursors [Reference Sinsermsuksakul, Heo, Noh, Hock and Gordon9, 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, Reference Rautanen, Leskela, Niinisto, Nykhen, Soininen and Utriainen33, Reference Hanninen, Mutikainen, Saanila, Ritala and Leskela34, Reference Kim, Yang, Powers, Davis, Lou and Gordon35, Reference Park, Heasley, Sun, Steinmann, Jaramillo, Hartman, Chakraborty, Sinsermsuksakul, Chua, Buonassisi and Gordon36, Reference Catherall, Harris, Hill, Johnson and Mahon37, Reference Yang38]. Files, Presentations Le Tulzo, Harold We noted that the orthorhombic SnS film starts to convert to the cubic phase at approximately 17% Ca in the cation mix and reaches full conversion at approximately 33% Ca. The exposure time for all the amidinate precursors are set to be 1 s, and H2S was exposed 3 s in the reactor. 3 Chemical and Physical Properties Expand this section. Recently, a phase diagram was proposed for (Sn,Ca)S films, showing a transition from an orthorhombic phase to a cubic phase as calcium content increased [Reference Holder, Siol, Ndione, Peng, Deml, Matthews, Schelhas, Toney, Gordon, Tumas, Perkins, Ginley, Gorman, Tate, Zakutayev and Lany27, Reference Vidal, Lany, Francis, Kokenyesi and Tate28, Reference Matthews, Holder, Schelhas, Siol, May, Forkner, Vigil-Fowler, Toney, Perkins, Gorman, Zakutayev, Lany and Tate29]. Figure 7: XRD spectra of (a) as-deposit and (b) annealed thin films (∼100 nm) with different Ca contents. Figure 3: Composition of (Sn,Ca)S deposited by Ca(F-amd)2 and Sn(A-amd)2 (a) at different temperatures using SnS:CaS dosing ratio of 20:1 and (b) using SnS:CaS dosing ratio ranging from 5:1 to 35:1 at substrate temperature of 212 °C. Figure 6 shows that the Ca contents are again higher than the values calculated from the separate growth rates of SnS and CaS using Ca(F-amd)2 and Sn(F-amd)2, indicating the presence of cation replacement as discussed in section “Film deposition using Sn and Ca precursors with different ligands”. "comments": true, However, the cubic phase is partially converted back into orthorhombic after annealing, and the α-SnS doublet peaks are recovered. 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. We found that (Sn,Ca)S transforms from an orthorhombic phase to a cubic phase as the Ca content increases. Place tablets under tongue at least 15 minutes before or 30 minutes after eating, brushing teeth, or drinking anything except water. After annealing at 400 °C in an H2S environment, the cubic alloy film undergoes a phase transition into the orthorhombic phase and its resistivity also decreases. 8(a) that the resistivity increases with increasing amount of Ca in the film. Schneider, Nathanaelle All peaks in the as-deposited film are from π-SnS, with the strongest peaks being (400), (222), (440), and (622). However, the pulsed laser deposition and co-sputtering methods used to make the (Sn,Ca)S thin films in those papers require high vacuum and demand high processing temperatures, leading to high processing cost, significant loss of Sn, and difficulties in controlling the stoichiometry of the films. This could be caused by phase separation into SnS and CaS at high temperature, which agrees with the thermodynamic argument by Vidal et al. These approximate materials prices are published to provide budgetary guidelines. "metrics": true, }. Events, (What Two kinds of tin sources were used: bis(N,N′-diisopropylacetamidinato)tin(II) and bis(N,N′-diisopropylformamidinato)tin(II), referred to as Sn(A-amd)2 and Sn(F-amd)2, respectively. This is consistent with the QCM data, where the Ca dose/purge step led to a net mass gain that is lower than what the mass gain would be without the cation exchange. This means that I dont have to remove spectator ions? ‒ In aluminum-killed, calcium treated steels, inclusions are typically compounds comprising Al 2 O 3, CaO, MgO, CaS, MnS, and TiN components ‒ Sulfur contents lower than 10 ppm are recommended to avoid back-modification of calcium aluminates into Al 2 O 3 (or MgO.Al 2 O 3) during continuous casting ‒ Excess calcium treatment makes (d) Cross-section SEM of an attempted solar cell with a 500-nm (Sn,Ca)S film deposited at 190 °C. 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].
