A section from the periodic table. More common semiconductor materials are shown in blue, except for Cu. A semiconductor can be either of a single element, such as Si or Ge, a compound, such as GaAs, InP or CdTe, or an alloy, such as SixGe(1-x) or AlxGa(1-x)As, where x is the fraction of the particular element and ranges from 0 to 1. Copper (Cu) is used for the electrical connections/wiring.
