Current Saturation in Cds
A calculation of the high electric fields found in domains beyond the onset of current saturation in piezoelectric semi-conductors is outlined. The calculation is a first principles one, deriving from Feynman’s exact polaron mobility formula. Special attention is given to explaining the motives behind an iteration scheme, that uses a classical like, constant drift velocity path as a zero-order approximation. The electrons are found to bunch in drifting localized potentials.
