Semiconductor charge injection physics

Fig. 6 Two models of charge recombination in a semiconductor particle. T are the trap sites, D is the excited dye molecule following electron injection In both cases cations are immobile, while electrons can move between trap sites on the surface of the nanoparticle by thermal activation to the conduction band. The model of [31] ([32]) is shown on the left (right). Reproduced with permission from [32]. Left figure (2001) The American Physical Society Right figure 2002 American Chemical Society...
