Abstract
Surface potential images of muscovite mica were taken using Amplitude Modulated Kelvin Force Microscopy (AM-KFM). Using this method, both topographic height and potential maps of the mica surface were taken simultaneously. The mica samples were rubbed by clean room type cotton q tip to generate contact electrification or CE. Carpet like formations on the surface with average potential of ±36mV was observed for the first time, and the charges dissipated after 3600 seconds through a grounded conductive surface.
