Abstract

The periodically poled ferroelectric wafer is a two-dimensional phononic superlattice. The important applications of such a solid include novel ultrasonic transducers at the micro/nano-scale for low intensity ultra-sonography, ferroelectric data storage, and development of very high frequency chips for next generation communication and information technologies, and others. Usually, the transformations between the electrical and mechanical energies are required in the applications. In this work, we find the frequency characteristics for an effective acousto-electric interaction in a two-dimensional phononic superlattice inserted in LiNbO3 wafer.
