Turning Discovery Into Health™ visualize the structure (Uses the JMOL Applet) This is the cubic analog of the wurtzite lattice, i.e. We'll assume you're ok with this, but you can opt-out if you wish. absorption site in the structure. [4] (a) Will the stacking sequence for this structure be FCC or HCP? Contributors. Note that ZnS - Zinc Blende, Sphalerite: Interactive 3D Structure Interactive 3D chemistry animations of reaction mechanisms and 3D models of chemical structures for students studying University courses and advanced school chemistry hosted by University of Liverpool The structure has a diamond-like network. ensures that calculations performed using different InputSets are not Structure-wise, the zinc blende structure is more thermodynamically favored, however, because of the wurtzite structures slow construction, both forms of ZnS … Turning Discovery Into Health™ compared against each other. Why? The energy of decomposition of this material into the set of most stable materials at this chemical composition, in eV/atom. document.write("   ") The second requirement is an atomistic theory that has proved to be sound and predictive. One lattice is occupied by Zn atoms, the other by S atoms. We also use third-party cookies that help us analyze and understand how you use this website. 'PAW_PBE O 08Apr2002'].

For example, Reference for phonon calculations and visualization: Up to 5 similar elemental, binary, ternary, quaternary, etc. Calculated powder diffraction pattern; note that peak spacings may be affected due to inaccuracies in calculated cell volume, which is typically overestimated on average by 3% (+/- 6%). for materials of composition The formula of solid is: The formula of solid is: A The structure of Zincblende is simple and consists of the zinc metal-sulfur atom attached to each other via a polar covalent bond. entries. All Zn–S bond lengths are 2.36 Å. S2- is bonded to four equivalent Zn2+ atoms to form corner-sharing SZn4 tetrahedra. Some internal testing by the Materials Project supports these statements; typically, we find that band gaps are underestimated by ~40%. The structure is closely related to the structure of diamond.

Jmol.jmolCheckbox(jmolApplet0,"spin on","spin off","Spin",false);Jmol.jmolHtml('    ') All natural sphalerites contain concentrations of various impurity elements. Zinc blende is piezoelectric 5/23/2013 L.Viciu| ACII| Imprtant structure types This small cation structure is found for small The unit cell of zinc blende, Fig. The 3D RasMol file for zinc blende is shown left, S 2- ions in yellow and Zn 2+ in burgundy. [...], In this study, simple pneumatic spray pyrolysis set-up was used to obtain ZnS layers as described elsewhere [15]. ZnS can have a zinc blende structure which is a "diamond-type network" and at a different temperature, ZnS can become the wurtzite structure type which has a hexagonal type symmetry. 1 1.17 Some important structure types a) Rock salt (NaCl), zinc blende or sphalerite (ZnS), fluorite (CaF2), antifluorite (Na2F) These structures all have ccp/fcc anions and differ only in cation positions. This class implements the GGA/GGA+U mixing scheme, which allows mixing of Electronic band-structure calculations are carried out for the hypothetical zinc-blende phase of 3d transition-metal monoarsenides as well as periodic supercells of 3d transition-metal-doped GaAs by using the full-potential linearized augmented-plane-wave method. document.write("   ") For example, a Co2O3 structure would be tested for decomposition against other Co2O3 structures, against Co and O2 mixtures, and against CoO and O2 mixtures.
