Its melting temperature is 937.4 C. Germanium has the diamond cubic crystal structure shown, an fcc lattice with a basis of two germanium atoms, one at (0,0,0) and the other at (1/4, 1/4, 1/4) in ...

In the zinc blend structure the sulphur ions form an fcc structure and the zinc ions occupy half of the tetrahedral sites in this structure to attain charge neutrality. The crystal has a lattice ...
