Photostimulated Quantum Effects in Quantum Wire with a Parabolic Potential
The quantum theory of the photostimulated effects in quantum wire has been studied based on the quantum kinetic equation for electrons with a parabolic potential V (z) = mω20z2/2 . In this case, electrons system in quantum wire is placed in a constant electric field (→E)0, an electromagnetic wave (→E) (t) = (→E) (e-iωt + eiωt) and in the presence of an intense laser field (→F) (t) = (→F) sin-t. In the presence of laser radiation and polarized electromagnetic wave can influence that current carrier, and do appear an electric field intensity vector (→E)0 with open circuit conditions. Hence, the analytic expressions of electric field intensity vector (→E)0 along the coordinate axes has been calculated. The dependence of the components (→E)0 on the frequency-of the laser radiation field, the frequency Ω of the electromagnetic wave field, the frequency ω0 of the parabolic potential are shown. From the analytic results, whenω0 ω0, the result will turn back to the photostimulated kinetic effects in semiconductors.
