Abstract
The band structure of InSb is computed by the empirical pseudopotential method (EPM) including a nonlocal correction. The pressure dependence of energy gaps and wave functions for InSb is then calculated. The pressure coefficient of the momentum matrix element between valence and conduction band is found to be very small as is usually assumed. The pressure coefficients of the parameters of electron scattering on short‐range potential centres associated with ionized impurities in InSb are also given in comparison with experimental estimations.
