We present a study of the effect of gold nanoparticles (Au NPs) on TiO<sub>2</sub> on charge generation and trapping during illumination with photons of energy larger than the substrate band gap. We used a novel characterization technique, photoassisted Kelvin probe force microscopy, to study the process at the single Au NP level. We found that the photoinduced electron transfer from TiO<sub>2</sub> to the Au NP increases logarithmically with light intensity due to the combined contribution of e ...[more]
