Acousto-Electric Device Physics and Applications

The acoustoelectric effect is a Coulombic interaction between free carriers and electric fields produced by phonons in solids. Recent advances in acoustoelectric devices that leverage state-of-the-art materials and microfabrication techniques have allowed reaching previously unattainable regimes of performance for acoustoelectric amplifiers and isolators, as well as new concepts of operation and applications. In this talk, I will review the basic physics underlying the acoustoelectric interactions, the most recent advances in the field and the materials and techniques that underlie them, and the future of acoustoelectric devices.
