Abstract
The magnetoresistance is one of the important properties of semiconductors. Starting from the hamiltonian for the electron-acoustic phonon system, we obtained the expression for the electron distribution function and especially the expression for the magnetoresistance in quantum wells with parabolic potential (QWPP) under the influence of electromagnetic wave (EMW) in the presence of magnetic field. We estimated numerical values and graphed for a GaAs/GaAsAl quantum well to see the nonlinear dependence of the magnetoresistance on the temperature of the system T, the amplitude E0 and the frequency Ω of the electromagnetic waves, the magnetic field B, the parameters of the quantum well and the momentum relaxation time τ clearly.
