Abstract:

A novel type of controllable phononic crystal controlled by external static electric field that induced periodic domains in ferroelectric thin film has been proposed. Finite element simulation results of frequency dependent of transmission coefficient and dispersion curves at first Brillouin zone are presented. The change of phononic band gap width via changing the electric field which induced the periodic domains in ferroelectric thin film was shown.
