This study constructs a new phononic crystal acoustic wave device that adopts a graphenelike structure and is composed of piezoelectric zinc oxide (ZnO) material. We employed the finite-element method to determine periodic boundary conditions. Following Bloch's theorem, we analyzed the acoustic wave propagation of the proposed graphenelike structure in the frequency domain to understand the band gap effect and oscillation behavior. We also investigated the band gap variation and modal distortion tendencies of the piezoelectric ZnO material in the two-dimensional graphenelike structure under the condition of changing chain structure diameters and bonding rod widths between the atoms columns to develop an optimal acoustic wave device.
