N Type , High Conductive GaSb Substrate , 3”, Dummy Grade

PAM-XIAMEN offers GaSb wafer – gallium antimonide which are grown by LEC(Liquid Encapsulated Czochralski) as epi-ready or mechanical grade with n type, p type or semi-insulating in different orientation(111)or(100).

Gallium antimonide (GaSb) is a semiconducting compound of gallium and antimony of the III-V family.It has a lattice constant of about 0.61 nm. GaSb can be used for Infrared detectors,infrared LEDs and lasers and transistors, and thermophotovoltaic systems.
