Germanium Wikipedia

Silicongermanium alloys are rapidly becoming an important semiconductor material for highspeed integrated circuits. Circuits utilizing the properties of SiSiGe junctions can be much faster than those using silicon alone. Silicongermanium is beginning to replace gallium arsenide (GaAs) in wireless communications devices.

Why silicon and germanium are semiconductors

Silicon is the principal component of common sand, and for this reason it is less expensive than other intrinsic semiconductor materials. But in such small quantities, raw material cost is not always decisive. Historically germanium was used as a semiconductor before silicon. The ’s whisker RF detector could be found in early crystal sets.
