Electronic band parameters: obtaining and peculiarities of InSb1-xBix crystal structures

Abstract

InSb1-xBix solid solutions monocrystal structures with (Delta) Eg80K equals 0,12eV were obtained using the modified Czochralski, zone and laser melting methods. A band structure of semiconductor InSb1-xBix substitution solid solution is calculated by the empirical pseudopotential method. Spin-orbital interactions are also included in local calculations. Using the virtual-crystal approximation the composition and temperature dependencies of energy gap are studied. The results are in good agreement with available experimental data.
