Our group develops novel radio-frequency microelectromechanical (RF-MEMS) acoustic resonators using a variety of high quality piezoelectric, semiconducting, multiferroic, wide bandgap, and superconducting materials that are grown in-house. We use these devices for fundamental and applied research on a variety of topics including materials discovery and characterization, conventional RF-acoustic signal processing, sensing, and quantum acoustodynamics. Our group and the Laboratory possess extensive computational resources as well as facilities and equipment for materials growth, device fabrication, and characterization.

 

We invite innovative proposals involving multi-physics phenomena in advanced RF acoustic resonators (e.g.: phonon-photon, phonon-magnon, or phonon-electron coupling). We are especially interested in understanding and utilizing the physics of RF-MEMS resonators under regimes that enable coupling between quantum states (spin or superconducting qubits), and acoustic phonons. A selection of our group's recent work is given below, but proposals need not be restricted to these topics/projects.
