CY1071 Germanium Crystal Sheet (Ge Crystal Sheet)

Germanium Crystal Sheet Description

Germanium Crystal Sheet can be used as windows, lenses, prisms, etc. for infrared detection and imaging systems. Infrared single-crystal germanium is widely used in 2um to 20um infrared optics and laser systems. In addition, single-crystal germanium has a good transmittance within the infrared and far-infrared bands.

Germanium single-crystal growth 

Now the company has a single-crystal furnace, with an annual output of 25 tons of germanium single crystal, and 5 tons of silicon single crystal. Using advanced equipment at home and abroad, and decades of crystal preparation technology, with its own district in molten germanium ingots as raw materials, production: electronic grade germanium single crystal: resistivity range 0.25 to 50 ohm-cm, the resistivity uniformity <15%, crystal to the (111), crystal orientation deviation < Shan'xi, dislocation density, 1000 ~ 3500 / L.
Minority carrier lifetime >150. Germanium single crystal is mainly used in the production of germanium transistors because the electron and hole transfer rate of germanium is higher than that in high-speed switching circuits.
