A Study on Phase Change Materials at Low Thermal Mass with Micro-Electro-Mechanical Resonators
DownloadSpring 2020
Micro-electromechanical systems or MEMS is a modern technology used to create tiny, integrated devices or systems that combine mechanical and electrical components. These miniaturized devices can sense, control and actuate on the micro and nano scales, and generate observable effects on the macro...

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...
