Abstract
Formulas are derived for the calculation of free carrier absorption in semiconductors with ellipsoidal constant energy surfaces, including the effects of non-parabolicity, for all important scattering mechanisms. It is shown that simple expressions for the absorption coefficient follow from a mathematically exact formulation only in case of acoustic, nonpolar optical, and inter-valley scattering. Simple, approximate expressions are also suggested for the evaluation of the absorption coefficient in the case of polar optical phonon and impurity scattering.
