Spatial periodicity of surface motility. a Amplitude of the switching dynamics, probed with LSI, perpendicular (red line) and parallel (black line) to the electrodes. The motility is measured by 〈d2(f = 1 Hz)〉, which is averaged over the orthogonal direction. The periodicity in d2 matches the striated IDE pattern, as confirmed by corresponding power spectra (b): for the x-direction, a sharp peak is visible at 1/8.1 μm−1, representing the distance between electrodes. By contrast, the motility along electrodes lacks clear periodicity
