germanium | Properties, Uses, Facts |

Germanium, a chemical element between silicon and tin in Group 14 (IVa) of the periodic table, a silverygray metalloid, intermediate in properties between the metals and the nonmetals. It did not become economically significant until after 1945, when its properties as a semiconductor in electronics were recognized.

4. Doping of GroupIVBased Materials

SiliconGermanium Alloys Silicongermanium (SiGe) is a IVIV compound semiconductor which offers enhanced carrier mobility and a higher dopant solubility compared to pure silicon. The remarkable potential of the SiGe material arises from the possibility to modify its properties by altering the composition.
