Electronic transport is controlled by trapping and detrapping of photogenerated electrons in interfacial bandgap states, distributed in energy. The localization time of a trapped electron is controlled by the steady-state light intensity and interfacial kinetics. 关键词: carbon clusters; field evaporation; graphite; scanning tunneling microscopy microscopy; COLLOIDAL TIO2; PHOTOELECTROCHEMICAL CELLS; FILMS
