The Magneto-electric Properties of Infinite Semi-parabolic Plus Semi-inverse Squared Quantum Wells in the Presence of a Strong Electromagnetic Wave
Main Article Content
Abstract
The Magneto-electric properties of infinite Semi-parabolic Plus Semi-inverse Squared Quantum wells (ISPPSISQW) in the presence of a strong Electromagnetic Wave (EMW) are theoretically investigated by using Quantum Kinetic Equation. The system is subjected to an IEMW E, a magnetic field , and a cross DC electric field E. The electron-optical phonon scattering is considered. The general expression of the Magnetoresistance (MR) is presented as a function of the temperature, the external magnetic field, the photon energy, and the intensity of the strong EMW as well as characteristic parameters of ISPPSISQW. The theoretical result for a specific GaAs/GaAsAl ISPPSISQW is achieved by using a numerical method. The computational result demonstrates that the maximum peaks appear satisfying the magneto-phonon-photon resonance condition. The resonance peak's position remains unaffected by temperature variations and changes by confinement frequency and by electric field; the MR decreases as temperature increases nonlinearly.
Keywords: Magnetoresistance, magneto-phonon-photon resonance, infinite semi-parabolic plus semi-inverse squared quantum wells, electromagnetic wave, quantum kinetic equation.
