Query: Screening, nonadiabaticity, and quantized acoustoelectric current   Quantized single-electron transport driven by surface acoustic waves (SAW)
through a pinched-off narrow constriction is studied theoretically. Long-range
Coulomb interaction causes the tunneling coupling between the two-dimensional
electron gas (2DEG) and the moving minimum of the SAW-induced potential to
decay rapidly with time. The energy scale, associated with the characteristic
time of this decay, controls both the width of the transition regions between
the plateaus and the slope of the plateaus. This sets a limit for the accuracy
of the quantization of acoustoelectric current at low temperature.
