Germanium Facts
Wednesday March 31, 2004
Germanium belongs to the class of elements that are called metalloids or semimetals. Like other elements in this group, trace impurities can be added to germanium to produce semiconductors. Germanium and germanium oxide are transparent to infrared light and exhibit other desirable optical properties, so the element is used in infrared spectrometers and lenses.

Today Germanium is most widely used in the semiconductor industry.Pure Ge can appreciably conduct electricity only at high temperatures.If we want to utilize it at room temp then a process called ‘doping’,is put into practice.Doping with a Group-13,trivalent impurity produces a p-type semiconductor whereas doping with a Group-15 impurity produces a n-type semiconductor.These combinations are further used for the formation of junction diodes and transistors which are most widely used in creating electronic equipments.
