| Abstract: | Round-trip acoustoelectric gain has been observed in n-GaAs filaments oriented along the [110] axis. The special conditions required for this effect are obtained through partial conversion upon reflection of active transverse to non-active longitudinal waves. Experiments in which the relative contributions of the two reflected modes to round-trip gain is varied are described. |
