Light Absorption near Threshold with Phonon Participation for Impurities in Semiconductors
It is presented a simple model for the calculation of the transition rate for impurities in semiconductors in which electron-phonon interaction is taken into account in a second order time dependent perturbation theory. This result shows the explicit dependence of the transition rate on the phonon d...
