Temperature dependence of the piezoelectric shear coefficient of PMN-PT, LiNbO3 and PZT transducers
DownloadSpring 2014
Piezoelectric transducers are widely used as sensitive detectors of stress and to generate nanometer scale displacements. However, their piezoelectric coefficients often decrease substantially at cryogenic temperatures, limiting their performance in, e.g., low temperature STMs (scanning tunneling...
