Band-edge tuning in self-assembled layers of Bi(sub 2)S(sub 3) nanoparticles used to photosensitize nanocrystalline TiO3

Article Abstract:

Self-assembled layers of Bi(sub 2)S(sub 3) nanoparticles are used to sensitize nanocrystalline titanium dioxide, replacing the ruthenium dye used in conventional dye-sensitized solar cells. The results suggest that band-edge tuning might form a useful part of strategies designed to exploit semiconductor quantum dots as sensitizers.

Ba adsorption on the stoichiometric and defective Ti[O.sub.2] (110) surface from first-principles calculations

Article Abstract:

A density functional study of Ba adsorption on the stoichiometric and defective Ti[O.sub.2] (110) surface is presented. The findings reveal that for the stoichiometric surface two equivalent adsorption patterns are found, whereas only one is found for the defective surface.
