We study the current density of charge carries of the radio electrical effect in parabolic quantum wells (PQW) subjected to a dc electric field E ~ 0 and in a linearly polarized ~ electromagnetic wave (EMW) (E(t) = E(e ~ −iωt iωt ~ ~ + e ), H(t) = [~n, E(t)]), (~ω ¿ ε̄; ε̄ is an aver- age carrier energy, in this paper), in the presence of a laser radiation F~ (t) = F~ sin Ωt; Ωτ À 1 (τ is the characteristic relaxation time). By using the quantum kinetic equation method for electrons interacting with acoustic phonon at low temperatures, we obtain the expressions for the drag of the charge carriers in case the electron gas is completely degenerate. The dependence of the cur- rent density on the intensity F and the frequency Ω of the laser radiation, the frequency ω of the linearly polarized EMW, the frequency ω0 of the parabolic potential are obtained. The analytic expressions are numerically evaluated and plotted for a specific quantum wells, GaAs/AlGaAs, to show clearly the dependence of the current density of charge carriers on the radioelectrical effect on above parameters. The results of current density calculation in this case are compared with bulk semiconductors to show the dissimilarity.
