Abstract
We report the experimental observation of resonant coupling and amplification of acoustic surface waves on a piezoelectric with electron surface waves on an adjacent semiconductor in a transverse magnetic field. Room‐temperature measurements were made at 30 and 150 MHz on a LiNbO3–GaAs structure, using magnetic fields of up to 144 kG.Keywords
