Abstract
Acoustic devices are popular as components in cellular communication transceivers due to their small size, low insertion loss, and high resonant frequencies. Presented are initial efforts to study a ferroelectric semiconductor, α-In2Se3, for use in acoustic devices. Discussed are a process for the exfoliation of α-In2Se3 flakes, followed by a bilayer lift-off process for patterning metal electrodes. The electrical properties of the exfoliated flakes will be characterized and integrated into surface acoustic wave devices to study acousto-electric interactions and model their potential for magnet-free RF circulators, enabling compact simultaneous transmit and receive radios.
