2inch diameter 50.8mm 500um thickness InAs substrates,Indium arsenide InAs crystal wafer, N-type 3inch 0.6mm InAs wafer,10x10mm square InAs wafers
------------------------------------------------------------------------------------------------------------------------------
InAs single crystal substrate can be grown InAsSb/In - AsPSb InNAsSb heterostructure materials,such as making 2 ~ 14 microns of infrared wavelength light-emitting devices, with InAs single crystal substrate can also be grown epitaxial AlGaSb superlattice materials, production for infrared quantum cascade lasers.
ZMKJ can provides InAs wafer ( Indium Arsenide ) to optoelectronics industry in diameter up to 3 inch .
InAs crystal is a compound formed by 6N pure In and As element and is grown by Liquid Encapsulated Czochralski ( LEC ) method with EPD < 15000 cm -3 . InAs crystal has high uniformity of electrical parameters and low defect density , suitable for MBE or MOCVD epitaxial growth . We have "epi ready " InAs products with wide choice in exact or off orientation , low or high doped concentration and surface finish . Please contact us for more product information .
