Abstract
The interaction of electrons with LO phonons, plasmons and coupled LO-phonon/plasmons is described. A simple unifying theory describing long-wavelength excitations in bulk polar semiconductors is developed using results from crystal optics. Predictions pertaining to hot electron relaxation via the emission of coupled modes are shown to be in excellent agreement with recent key investigations.Keywords
