Abstract : The patent relates to acoustic surface waves produced in a lossy piezoelectric material and guided therealong due to the interaction between the acoustic waves and a drift electron flow established in an adjacent semiconductor material. The drift electrons impart energy sufficient to sustain propagation of the acoustic surface waves only in the desired direction defined by the drift electron path or channel.
