2-4inch Gallium antimonide GaSb Substrate Single Crystal Monocrystal for Semiconductor
InAsSb/In-AsPSb, InNAsSb and other heterojunction materials can be grown on InAs single crystal as the substrate, and an infrared light-emitting device with a wavelength of 2 to 14 μm can be fabricated. The AlGaSb superlattice structure material can also be epitaxially grown by using InAs single crystal substrate. Mid-infrared quantum cascade laser. These infrared devices have good application prospects in the fields of gas monitoring, low-loss fiber communication, etc. In addition, InAs single crystals have high electron mobility and are ideal materials for making Hall devices.
Applications:
InAs single crystal can be used as a substrate material to grow a
heterostructure material such as InAsSb/InAsPSb or InAsPSb to
fabricate an infrared light-emitting device having a wavelength of
2-12 μm. The InAsPSb superlattice structure material can also be
epitaxially grown by using InAs single crystal substrate to
fabricate a mid-infrared quantum cascade laser. These infrared
devices have good application prospects in the field of gas
detection and low loss fiber communication. In addition, InAs
single crystals have high electron mobility and are an ideal
material for making Hall devices.
Features:
1. The crystal is grown by liquid-sealed straight-drawing
technology (LEC), with mature technology and stable electrical
performance.
2, using X-ray directional instrument for precise orientation, the
crystal orientation deviation is only ±0.5°
3, the wafer is polished by chemical mechanical polishing (CMP)
technology, surface roughness <0.5nm
4, to achieve the "open box ready to use" requirements
5, according to user requirements, special specifications product
