Paper Abstract

The non-commutation relationship between the Hamiltonian of the system and the electron momentum operator in the confinement z-direction was taken into account using random variables in the calculation of electron scattering by polar optical phonons in quantum wells. The rate at the onset of phonon emission is found to be 3 times smaller than previously reported. Furthermore, this rate becomes an increasing function of initial electron energy instead of a decreasing function.
