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 ...

The structure has face-centered cubic symmetry, and is a little heavy to understand. The general formula is AB 2 O 4. The oxygens form an fcc lattice. The A cations occupy tetrahedral holes, and the B ...

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 units of the cube edge. It can also be ...
