Enhanced Coupling Coefficient in Dual-Mode ZnO/SiC Surface Acoustic Wave Devices with Partially Etched Piezoelectric Layer
Surface acoustic wave (SAW) devices based on multi-layer structures have been widely used in filters and sensors. The electromechanical coupling factor (<i>K</i><sup>2</sup>), which reflects energy-conversion efficiency, directly determines the bandwidth of the filter and the...
