The Influence of the Electromagnetic Wave on the Quantum Acoustomagnetoelectric Field in a Quantum Well with a Parabolic Potential
The influence of the electromagnetic wave on the quantum acoustomagnetoelectric (QAME) field in a quantum well with a parabolic potential (QWPP) is investigated for an acoustic wave whose wavelength λ= 2π/q is smaller than the mean free path l of the electrons and in the region ql (>> )1 (where q is the acoustic wave number). The dependence of the QAME field EQAME on the frequency of external acoustic wave ωq, the temperature T, the magnetic field B, the amplitude E0 and frequency Ω of the electromagnetic wave are obtained by using the quantum kinetic equation. Numerical calculation is done, and the result is discussed for a typical AlAs/GaAs/AlAs QWPP. The computational results show that the dependence of the QAME field EQAME on the external acoustic wave frequency ωq, the frequency of electromagnetic wave Ω and the magnetic field B is non-monotonic, the cause of appearance peaks attributes the transition between mini-bands N→N′. The quantum theory of the QAME current in a QW is newly developed.
