A Closed Cavity Ultrasonic Resonator Formed by Graphene/PMMA Membrane for Acoustic Application
A graphene/poly(methyl methacrylate) (PMMA) closed cavity resonator with a resonant frequency at around 160 kHz has been fabricated. A six-layer graphene structure with a 450 nm PMMA laminated layer has been dry-transferred onto the closed cavity with an air gap of 105 [Formula: see text] m. The res...
