The Radioelectric effect in doped superlattice under the influence of confined phonon has been theoretically studied. The analytical expression for the Radioelectric field is obtained by using quantum kinetic equation method. The theoretical expression shows that the Radioelectric field in doped superlattice depends on the frequencies and amplitudes of the laser and the linearly polarized electromagnetic wave, the period of the superlattice and especially the quantum number m characterizing the phonon confinement. Numerical calculation is also applied for n-GaAs/p-GaAs doped superlattice. It is found that the Radioelectric field has multiple resonance peaks and increases as the increasing of quantum number m. All results are compared with those in normal bulk semiconductor as well as those in two dimensional systems when phonons are unconfined to show the differences.
