LGS and LGN Microresonators: Applications to High Temperature Nanobalances

Abstract:

New materials such as langasite and langanate crystals present some interesting perspectives for acoustic wave devices due to strong piezoelectric coefficients and due to the opportunity to work through a wide range of temperature. Theoretical formulations for temperature coefficients and electromechanical coupling coefficients of resonators are given in the case of thickness modes of vibration. Results are computed using two data sets of elastic, piezoelectric and dielectric constants. Orientations of BAW microresonators which give zero frequency shift versus temperature at 600°C are determined to serve as high temperature nanobalances.
