N Type , GaSb Wafer With Epitaxy-Ready Polished Surface , 4”, Prime Grade
PAM-XIAMEN manufactures high purity single crystal GaSb(Gallium Antimonide) Wafers 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. It has a band gap of 0.67 eV. Our standard wafer diameters range from 1 inch to 4 inches, wafers can be produced in various thicknesses and different orientations (100),(111),(110) with polished wafers and blank wafers. PAM-XIAMEN can produce wide range grades: prime grade, test grade, dummy grade, mechanical grade, and optical grade. PAM-XIAMEN also offer GaSb material to customer specifications by request, in addition to custom compositions for commercial and research applications and new proprietary technologies.
