Abstract
Taking into account electron scattering with confined plasmon-phonon coupled modes in a many-body formalism, the dark currents in a quantum well structure based on the Al0.27Ga0.73As∕GaAs heterojunctions have been calculated The nonparabolicity of the conduction band, finite temperature, and applied bias has been included in the calculation of the scattering rates. Good agreement with the experiments has been obtained by the inclusion of the nonparabolicity of the conduction band in the theory.
