The acoustomagnetoelectric (AME) field in a quantum well with an infinity potential (QWIP) has been studied in the presence of an external magnetic field. The analytic expression for the AME field in the QWIP was obtained by using the quantum kinetic equation for the distribution function of electrons interacting with the acoustic wave. The dependence of the AME field on the temperature T of the system, the frequency of the acoustic wave ωq, the quantum well width L and the external magnetic field B for the specific QWIP AlAs/GaAs/AlAs was achieved by using a numerical method. In the case of the dependence of the electromagnetic field on the external magnetic field and the frequency of the sound waves, the calculated results showed that this dependence was non-linear. These results were compared with those for the normal bulk semiconductor to show differences.
