摘要	Fourier grid Hamiltonian method is applied to calculate the quantized acoustoelectric current induced by surface acoustic wave (SAW) in a quasi-one-dimensional channel defined in a GaAs-Al(x)Ga(1-x)As heterostructure by split gate. Using simple models for the electrostatic potential barrier and piezoelectric potential, we obtain the first quantized plateau. Moreover, the role of the parameter beta, defined as a ratio of piezoelectric potential amplitude to the effective height of electrostatic potential barrier induced by split gate, is also examined during the calculations of the instantaneous ground state energies and the single-electron tunneling probabilities. The flatness of the plateau is also discussed. (c) 2006 Elsevier B.V. All rights reserved.
