Custom made Gallium antimonide GaSb single crystal substrate manufacturer from China

GaSb single crystal substrate
GaSb single crystals match the lattice constants of various ternary and quaternary, III-V compound solid solutions with bands in the 0.8~4.3um wide spectral range because of its lattice constant , because GaSb can be used as a substrate material Used to prepare lasers and detectors suitable for certain infrared optical fiber transmission, GaSb is also predicted to have a lattice-limited mobility greater than GaAs , making it a potential application prospect in the manufacture of microwave devices. The main growth methods of GaS single crystal materials include traditional liquid-sealed Czochralski technology ( LEC ), improved LEC technology, moving heating method / vertical gradient solidification technology ( VGF ) / vertical Bridgman
