- •
The Vp can be doubled with extremely large K2 for layered structure of relaxor based ferroelectric single crystal on diamond
- •
The unwanted resonances could be suppressed sufficiently by properly controlling structural parameters.
- •
Such layered structure makes relaxor crystals promising candidates for ultra-wideband RF SAW devices.
