Photochemical Behavior of TiO2- Following Electron and Hole Behavior

AACP Seminar Series

The behavior of photogenerated charge carriers in TiO₂ is a key issue in the optimization of efficiency of both photovoltaic devices and of redox processes which occur on the TiO₂ surface. Using a variety of physical methods we have been able to monitor processes such as charge transfer across the surface and electron-hole recombination within the TiO₂ bulk. These methods have allowed us to control the transport of electrons and holes at the semiconductor surface by causing band bending, using various adsorbed molecules.
