Paper Abstract

The decay of a zone-center LO-phonon in GaN into a TO phonon and a LA phonon is theoretically investigated, because its decay into two LA phonons is forbidden in GaN. A theoretical model is presented to study the effect of nonequilibrium LO and TO phonons on the electron energy relaxation rate. The individual contributions of A1 mode and E1 optical phonons in the overall electron energy relaxation processes are also discussed.
