2inch 3inch 4inch Germanium Substrates Semiconductor Wafers Custom CZ <100><110><111>
Germanium has good semiconductor properties. High-purity germanium is doped with trivalent elements (e.g., indium, gallium, boron) to obtain P-type germanium semiconductors, and pentavalent elements (e.g., antimony, arsenic, and phosphorus) doped to obtain N-type germanium semiconductors. They have high electron mobility and high hole mobility. High-quality germanium substrates can be used in concentrated photovoltaics (CPV), outer space solar panels, and high-brightness light-emitting diode (LED) applications.
Features
- The lattice constant is greater than that of silicon, which is conducive to the construction of heterostructures.
- The high electron mobility, about 3 times that of silicon, is conducive to the manufacture of high-speed electronic devices.
- The small bandgap width (0.67 eV) makes it suitable for infrared photoelectric detection and emission applications.
It is more sensitive to radiation and is suitable for radiation-sensitive electronic equipment.
The processing technology is relatively complex and the cost is high.
