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