Leveraging graphene’s high carrier mobility and the outstanding electromechanical coupling of (111)-cut PMN-PT, this platform achieves the highest AE current generation reported to date, which is a key parameter for acoustic charge transport applications. The platform comprises interdigitated transducers (IDTs) deposited and patterned on the bulk PMN-PT surface for launching SAW and a monolayer graphene film positioned within the SAW propagation region. Experimental measurements confirm generation of AE current and voltage within the SAW passband, with the AE current reaching up to 90 µA at an RF input power of 20 dBm, validating the effectiveness of the proposed platform. These results underscore the significant potential of graphene-on-PMN-PT SAW platform in developing novel acoustic charge transport devices for sensing, quantum, and signal processing applications.
