Article Title: Interferometric imaging of nonlocal electromechanical power transduction in ferroelectric domains

doi: 10.1073/pnas.1722499115

Figure Lengend Snippet: Interference of piezoelectric transduction in corral domains. (A–D) (Top) PFM-ph and (Bottom) MIM-Re images at f = 955 MHz of four closed LiNbO3 domains. Clear interference patterns due to the superposition of ripples around each DW are seen in the MIM-Re data. (Scale bars, 10 μm.) (E) Velocities of P-SAW and SAW calculated from the COMSOL eigensolver as a function of the angle between propagation vector k and the y axis on the z-cut LiNbO3 surface. (F) Line profiles in D, showing different oscillation periods along x direction (red) and y direction (blue). The result is consistent with the higher P-SAW velocity along the x axis than that along the y axis.
