Abstract
We consider the influence of a surface acoustic wave on the conductanc e through a ballistic quantum channel with an adiabatic geometry produ ced by split gates in a two-dimensional electron gas. The surface acou stic wave leads to a contribution to the conductance of the quantum ch annel. This contribution, called the acoustoconductance, is shown to o scillate as a function of the Fermi level, which is controlled by the gate voltage.
