    Abstract

    We evaluate the time-dependent potential at some quantum point contacts under irradiation of surface acoustic burst wave. The time and space dependences of the potential wave allow us to separate direct surface acoustic wave from other indirect acoustic wave and electromagnetic crosstalk. The technique can be used to separate the left-and right-moving acoustic waves.
