PAM-XIAMEN grows high quality Gallium Antimonide (GaSb) single crystal ingots. We also round, saw cut, lap and polish GaSb wafers and can supply an epi-ready surface quality. GaSb crystal is a compound formed by 6N pure Ga and Sb element and is grown by Liquid Encapsulated Czochralski ( LEC ) method with EPD < 1000 cm -3 . GaSb crystal has high uniformity of electrical parameters and low defect...
Direct diode lasers have some of the most attractive features of any laser. They are very efficient, compact, wavelength versatile, low cost, and highly reliable. However, the full utilization of direct diode lasers has yet to be realized. The poor quality of diode laser beam itself, directly affect its application ranges, in order to better use of diode laser stack, need a proper correction of op...
Highly tensile-strained sub-monolayer Ge nanostructures on GaSb have been grown by molecular beam epitaxy and studied by ultrahigh-vacuum scanning tunneling microscopy. Four different coverage rates of Ge nanostructures on GaSb are achieved and investigated. It is found the growth of Ge on GaSb follows 2D growth mode. The crystal lattice of the sub-monolayer Ge nanostructures is coherent with that...
Te-doped GaSb single crystals are studied by measuring Hall effect, infrared (IR) transmission and photoluminescence (PL) spectra. It is found that the n-type GaSb with IR transmittance can be obtained as high as 60% by the critical control of the Te-doping concentration and electrical compensation. The concentration of the native acceptor-associated defects is apparently low in the Te-doped GaSb ...
Orthogonal experiments of GaSb films growth on GaAs substrate have been designed and performed by using a low-pressure metal–organic chemical vapor deposition (LP-MOCVD) system. The crystallinities and microstructures of the produced films were comparatively analyzed to achieve the optimum growth parameters. It was demonstrated that the optimized GaSb thin film has a narrow full width at half maxi...
