 General Information

1.  MATERIAL OVERVIEW  

Characteristics:

Lustrous, hard, grayish-white solid metalloid in the carbon group, chemically similar to its group neighbors tin and silicon. Purified germanium is a 'p-type' semiconductor material. Conductivity depends largely on added impurities. Attacked by nitric acid and aqua regia, but stable in water, acids, and alkalies in absence of dissolved oxygen, low toxicity.

Applications:

Isolated germanium is mainly used as a semiconductor material for transistors. The first generation of semiconductors were based solely on germanium. However, most of today’s semiconductor production is based on silicon and germaniums use in electronics are in fibre-optic systems, infrared optics and in solar cell applications..
