    GaAs B single crystal substrate
    Update Time : 2020-06-17 View : 1975


    The lattice constants of GaSb single crystal match the lattice constants of solid melts of various ternary, Quaternary and III-V compounds with band gaps in the range of 0.8-4.3um As a substrate material, GaSb can be used as a laser and detector for infrared fiber transmission. The lattice confinement mobility of GaSb is higher than that of GaAs, which makes it have a potential application in microwave devices.
