The Dependence of the Acoustomagnetoelectric Current on the Parameters of a Cylindrical Quantum Wire with an Infinite Potential in the Presence of an External Magnetic Field

The acoustomagnetoelectric effect in a cylindrical quantum wire with an infinite potential in the presence of an external magnetic field is investigated by using Boltzmann kinetic equation for an acoustic wave whose wavelength lambda = 2 pi/q is smaller than the mean free path l of the electrons and hypersound in the region ql >> 1, (where q is the acoustic wave number). The analytic expression for the acoustomagnetoelectric current I-ame is calculated in the case: relaxation time of momentum tau is constant approximation and degenerates electrons gas. The nonlinear dependence of the expression for the acoustomagnetoelectric current I-ame on the acoustic wave numbers q and on the parameters of the cylindrical quantum wires is obtained. Numerical computations are performed for AlGaAs/GaAs cylindrical quantum wire with an infinite potential. The results are compared with the normal bulk semiconductors and the superlattices to show the values of the acoustomagnetoelectric current I-ame in the cylindrical quantum wire are different than they are in the normal bulk semiconductors and the superlattices.
