The Influence of an Electromagnetic Wave on the Acoustoelectric Current in a Rectangular Quantum Wire with an Infinite Potential
The analytic expression for the acoustoelectric(AE)current in the presence of an electromagnetic wave(EMW)induced by the electron-external acoustic wave(external phonons)interactions and electron-internal acoustic wave(internal phonons)scattering in a rectangular quantum wire(RQW)with an infinite potential is calculated by using the quantum kinetic equation for electrons.The dependence of the AE current on the temperature,the external acoustic wave frequency,the frequency of the EMW and the parameters of the RQW is analyzed.The theoretical results are numerically evaluated,plotted and discussed for the specific rectangular quantum wire with an infinite potential GaAs.These results are also compared with those for normal bulk semiconductors and RQW in the case of the absence of the EMW to show difference.
