However, it is difficult for the quartz substrate to scale-down by photolithography. In this article, we develop another type of piezoelectric material, PbZrxTi(1-x)O3, as a thin film by sol-gel route to replace the quartz crystal as a resonator. The novel hydrothermal annealing with microwave system is proposed to substitute the conventional furnace annealing.

TOD is positively correlated with its length. The calculations presented here allow for the determination of the maximum thickness of crystal that may be used in the autocorrelation system.
