This paper addresses the electron-phonon interaction when a perpendicular electric field is applied across a quantum well (QW). An applied perpendicular electric field redistributes the one-dimensional density of states in position and energy within a QW. The redistribution of the one-dimensional density of states modifies the calculation of the initial and final states in the electron-phonon interaction. The overall result is to increase the scattering rate between the electrons and phonons while adding additional characteristics to the shape of the phonon scattering time
