Abstract

A formula is derived for the calculation of free carrier absorption in semiconductors with ellipsoidal energy band structure, including the effects of electron screening, when the dominant scattering mechanism is due to polar modes. Computational results are also presented which show that the magnitude of the FCA is significantly affected by the mass anisotropy coefficient.
