Diamond Crystal Structure
Background image of page 14
Semiconductor Crystal Structures Diamond structure – crystalline structure of Si, Ge, diamond It is a face centered cubic crystal with two atoms per site. It results from the covalent bonding of the atoms in a tetrahedral arrangement. The tetrahedron is the basic building block of these materials. Silicon

Compound Semiconductors Many compound semiconductors are formed in the zincblende crystal structure as shown above. This structure is similar to the diamond structure except every other atom site alternates between the two atoms that make up the crystal. It is a fcc structure with 2 atoms per site. GaAs
