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 cat’s whisker RF detector could be found in early crystal sets.

Semiconductor - Wikipedia

A semiconductor material has an electrical conductivity value falling between that of a conductor, such as metallic copper, and an insulator, such as glass.Its resistance falls as its temperature rises; metals are the opposite. Its conducting properties may be altered in useful ways by introducing impurities ("doping") into the crystal structure.When two differently-doped regions exist in the ...
