Surface acoustic wave device having negative temperature coefficient of decay |
摘要 |
A surface acoustic wave device using a quartz substrate has a larger electromechanical coupling coefficient than conventional devices. The SAW device is constructed by forming a thin ZnO film on a quartz substrate and disposing comb-like electrodes on the ZnO film.
