Title: 'hot Phonon' Contribution To Urbach's Tails In Semiconductors
Author: Ramos J.G.
Luzzi R.
Abstract: We consider electron-hole recombination in semiconductors under high injection levels of electrons and holes interacting with 'hot LO-phonons'. It is shown that the increasing value of E0, an energy parameter which characterizes the exponential low energy edge in the luminescence spectra, with laser light intensity is the result of the increasing concentration of phonons in excess of equilibrium. Dependence of E0 with the effective temperature T* of the phonons is given. Furthermore, it is shown that the electron-phonon interaction also contributes to the shift of the spectra towards lower energies. © 1974.
