Abstract

In this study, based on the quantum kinetic equation approach, we systematically present the radio-electric effect in asymmetric semi-parabolic quantum wells under the influence of a laser radiation field taking into account the electron-longitudinal optical phonon scattering mechanism. The numerical results show that the blue-shift of the maximum peaks in the photon energy range is less than 60 meV. The height of maximum peaks increases according to an exponential rule, depending nonlinearly on the structural parameters of the asymmetric semi-parabolic quantum wells. In the photon energy range greater than 100 meV, the saturated radio-electric field increases with temperature and geometric parameters of the quantum well. The results show the differences between symmetric and asymmetric semi-parabolic quantum wells, highlighting the influence of asymmetric structures on radio-electric effects in two-dimensional quantum well systems.
