Product Details

Basic information

Germanium monocrystalline is a crystal which is get by CZ or VGF method, use high-purity germanium as raw material.

Germanium monocrystalline is the most widely used as infrared optical material all around the world because of its extraordinary advantages such as: high index of infrared refraction,infrared wide transmission,low absorption coefficient,low dispersion rate,processing easily etc. Typically in shape of water,lenses,prisms and films for thermal imager,infrared radar,optical devices,even used in military field.

Application

1.Germanium monocrystals can be used as transistors and are the first-generation transistor materials.

2.Monocrystalline germanium finds significant applications in infrared optical components (such as thermal imagers and laser windows) and γ radiation detectors, covering military airborne/shipborne equipment, civilian security surveillance, and night driving assistance scenarios.

3.Germanium wafers made from germanium monocrystalline are used in the photovoltaic field for space solar cells, while germanium tetrachloride products for optical fibers serve optical communication modules. Compound semiconductor materials such as gallium arsenide wafers and indium phosphide wafers are used in the manufacturing of semiconductor devices.
