• The longitudinal radioelectrical efffect in a parabolic quantum well (PQW) has been studied, based on the quantum kinetic equation for electrons under the action of a linearly polarized electromagnetic wave (EMW) and an intense laser field. Analytic expressions for the density of the current associated with the drag of charge carriers for the case of electron optical phonon scattering is calculated. The dependence of the current density on the intensity F and the frequency O of the laser radiation field, the frequency ω of the linearly polarized EMW field, the frequency of the parabolic potential, the temperature T of the system are obtained. The analytic expressions are numerically evaluated and plotted for a specific quantum wells, GaAs/AlGaAs. All the results of PQW are compared with semiconductors builk and superlattice shows that the difference.
