Germanium is lustrous, hard, grayish-white solid metalloid in the carbon group, chemically similar to its group neighbors tin and silicon. The purified germanium is a ‘p-type’ semiconductor material. The conductivity depends largely on added impurities. It has the same cubic crystal structure as diamond.
It has a high refractive index and is high transparency to infrared radiation. Germanium is a semiconductor and is one of the purest metals on earth (99.99999999999%).
