摘要
Acoustic surface waves are produced in a lossy piezoelectric material and are guided therealong due to the interaction between the acoustic waves and a drift electron flow established in an adjacent semiconductor matrial; i.e., 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.
