Surface potential of PPy-diamond heterojunction as function of illumination and time. (a) Three-dimensional representation of surface potential map, and (b) temporal potential profiles that were obtained via KFM scanning across PPy-diamond and bare diamond surface (where PPy was removed) under repeated illumination switching. The positions of profiles are indicated by lines and arrows in the image.
