Abstract Analytic eigenfunctions describing polar optical modes in a thin ionic slab derived by Fuchs and Kliewer are used to compute the electron scattering rates. The scattering rates turn out to… (More)
Numerical calculations have been made of the rates of scattering and momentum relaxation of electrons caused by unscreened polar optical phonons in quasi-two-dimensional layers, using a simple… (More)
The Auger transition at a He-type defect, deeply binding two electrons, is investigated, with the aim of assessing the dominant factors affecting the magnitude of Auger cross sections. The usual… (More)
Abstract The present work is an extension of previous analysis for quasi-2D wells to quasi-1D wells. Analytic expressions are determined for the scattering rate due to the deformation potential… (More)
Abstract It is shown that the ground state of deep impurities with potentials attractive to electrons is always s-like, irrespective of whether the impurity occupies anion or cation sites. The… (More)
It is shown that the Auger transition probability for excitons bound to deep neutral impurities cannot be derived by extrapolating the results obtained for the series of shallow donors and acceptors.… (More)
