Abstract

We theoretically study the energy relaxation of hot electrons via LO-phonon emission in two-dimensional GaN systems. We employ a model in which electrons and the lattice are in equilibrium separately, and the effective electron temperature is much larger than the lattice temperature. We include the dynamical screening of electrons, electron-phonon interactions reduced phonon self-energy correction, the hot-phonon, and the finite-size effects. The power loss to acoustic phonons is also considered.
