Abstract

Experimental results of the measured surface acoustic wave (SAW) acoustoelectric effect (AE) using single-layer thin-film graphene on 128°, Y-cut, and X-propagating lithium niobate (128-LN) are presented. The use of an AE amplifier in SAW communication devices, especially in gigahertz bands, could make fundamental advancements in radios, sensors, and other applications. Experimental results at 1350 MHz show the delay line asymmetry of 3 dB, given as the ratio of the forward versus reverse peak SAW frequency response, with an applied dc voltage on the graphene film.
