Microelectromechanical Resonators Having Degenerately-doped And/or Eutectic Alloy Resonator Bodies Therein

A microelectromechanical resonator includes a resonator body having a semiconductor region therein that may be degenerately doped with boron. This high level of doping facilitates the formation of a eutectic alloy within the resonator body in response to resistive heating. The formation of a lattice-strained eutectic alloy within the resonator body supports reductions in the temperature coefficient of frequency (TCF) of the resonator over a relatively large temperature range.Georgia Tech Research Corporatio
