The band structure and electron density of InSb_1-xBi_x solid solutions

摘要

A band structure of semiconductor InSb_1-xBi_x substitution solid so- lution 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 dependences of energy gap are studied. The results are in good agreement with available experimental data.
