Germanium: Semiconductor milestone -- ScienceDaily

Germanium is one material being considered to replace silicon because it could enable the industry to make smaller transistors and more compact integrated circuits, Ye said.

Why is silicon preferred over germanium in preparing diode ...

Silicon is relatively easy and inexpensive to obtain and process, whereas Germanium is rare material that is typically found with copper, lead or silver deposits. Because of its rarity, germanium is more expensive to work with, thus making germanium diodes more difficult to find (and sometimes more expensive) than silicon diodes.

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.
