We have studied magneto-thermoelectric effects in quantum well in the
presence of electromagnetic wave. The analytic expression for
Ettingshausen coefficient (EC) in the Quantum Well with parabolic
potential (QWPP) in the presence of Electromagnetic wave (EMW) is
calculated by using the quantum kinetic equation for electrons. The
dependence of EC on the frequency, the amplitude of EMW, the Quantum
Well parameters and the temperature are obtained. The results are
numerically calculated, plotted, and discussed for GaAs/GaAsAl Quantum
Well to clearly show the dependence of EC on above parameters and the
results in this case are compared with the case in the bulk
semiconductors. We realize that as the temperature increases, the EC
decreases. The results show appearance of the Shubnikov–de Haas (SdH)
oscillations when we survey the dependence of EC on the magnetic field.
