ZN Blende/Sphalerite Unit Cell
SKU: 68789W
The Indigo® 68789W sphalerite (zinc blende) unit cell molecular model shows Td point group symmetry, face-centered cubic crystal structure, and tetrahedral coordination in II-VI semiconductors. It is an ideal study tool for solid state chemistry, crystallography, semiconductor physics, and materials science.
The Indigo® 68789W model builds the sphalerite (zinc blende, α-ZnS) unit cell, a cubic polymorph of zinc sulfide. It belongs to the Td point group and crystallographic space group F4?3m and illustrates a face-centered cubic sublattice. The yellow S2- ions form the FCC sublattice while silver Zn2+ ions occupy half of the tetrahedral interstitial sites, giving each ion a coordination number of four. ZnS is a II-VI semiconductor with a sphalerite structure that is a thermodynamically stable polymorph below 1020°C. Above that it transforms to the hexagonal wurtzite structure.
Indigo Instruments has held inventory of genuine Cochranes of Oxford (Orbit) parts for 30+ years (See Skeletal (Orbit/Minit)) that are compatible with every molecular model we have sold since day 1. This level of quality may appear expensive but no parts support from other vendors costs even more.
