Silicon (Si)

Silicon is grown by Czochralski (CZ) pulling techniques. CZ Silicon is commonly used as substrate material for infrared reflectors and windows in the 1.5 – 8 micron region. The strong absorption band at 9 microns makes it unsuitable for CO₂ laser transmission applications, but it is frequently used for laser mirrors because of its high thermal conductivity and low density. Silicon is widely used in detector/sensor devices, MEMS fabrication, opto-electronic components, integrated circuits and solar cells.

Vital Materials specializes in supplying a number of forms and sizes to meet our customers' requirements at a reasonable price. By doping with Boron (P-type) and Phosphorus (N-type), we made our Silicon products ideal for optical use because of its resistivity and broad transmission range.
