The influence of the confined optical phonons on the Radioelectric effect in a cylindrical quantum wire (CQW) subjected to a dc electric field, a linearly polarized electromagnetic wave and varying laser radiation, has been theoretically studied by using the quantum kinetic equation method. The analytical expression of the Radioelectric field (REF) is obtained as a function of the external electromagnetic waves energy, the temperature of the system, the wire’s radius and especially the quantum numbers $n, m$ which characterize the effect of phonon confinement. Numerical evaluations for the GaAs/AlAs cylindrical quantum wire show that the confined optical phonons enhance the probability of electron scattering, thus, lead to an increase of the REF when compared to the case of bulk phonons.
