Abstract
AbstractAn analysis of the experimental data for InSb and of the theoretical considerations used for the determination of the deformation potential constant of the conduction band ϵl is made. It is shown that the correctly calculated value of |ϵ1| is about 30 eV. The small values of |ϵ1| obtained in some works by observing transport phenomena in the hot electron region at lattice temperatures of 4.2 K in samples with electron densities n from 1015 to lo17 cm−3 for which the Boltzmann transport equation is valid, are caused by a distortion of the bottom of the conduction band due to fluctuations of the impurity potential.
