Dr. Tabrizian will present an overview of semiconductor micromechanical resonators and acoustic phonon traps. The phonon-level formulation of vibration modes and dissipation mechanisms will be described. Performance sensitivity of phonon traps to physical interactions will be discussed and followed by demonstration of several applications in environmental sensing and physical gauging. Moreover, temperature and dissipation compensation techniques for realization of highly-stable low-loss micro-resonators for frequency reference purposes will be reviewed.
