A model for a unified quantum description of macroscopic and microscopic systems

Abstract

The influence of electromagnetic wave (EMW) on the acous- tomagnetoelectric (AME) effect is studied theoretically in a quantum well. The expression of the AME field is obtained. The dependences of the AME field on the temperature of system, the frequency of acoustic wave, the frequency and intensity of electromagnetic wave and the parameters of a Quantum well are nonlinear. These dependences in the case of QW are different and more complex than in the case of bulk semiconductor. The results are numerically calculated and discussed for an GaAs/AGaAs QW. The graph of the dependence of the AME field on the frequency of acoustic wave shows that the changes of external magnetic field drag on the change of value of AME field and the change of the position of AME field. The value of the AME field in case with the intensity of EMW is much bigger than in case without the intensity of EMW.
