Abstract :
We introduce a new metric for judging material suitability for high frequency resonator use, and tabulate its value for a number of resonator materials. The new metric combines all the physical quantities associated with acoustic wave propagation in piezocrystals: mass density, dielectric permittivity, piezoelectric modulus, elastic stiffness, and viscosity. Use of this metric to rank materials yields some nonobvious and counterintuitive conclusions with implications for the directions the technology might take, and where the emphases for future progress might be placed
