The face centered cubic (FCC) unit cell begins with a totally different layer, one that is packed much more efficiently. This figure shows the basic layer that will be repeated throughout the entire ...

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 ...

Hexagonal close packing is one of two crystal structures that derive from stacking close-packed-planes of hard sphere atoms. In the HCP structure only two stacking ...
