UPS of one monolayer PbSe QDs (3.4 nm diameter) assembled on the TiO2(110) surface. The oleic acid capping molecules have been removed by reaction with hydrazine (red) or replaced with EDT (blue). Also shown is a spectrum for clean TiO2(110). Energy scale is referenced to the substrate Fermi level. Experimental details can be found in refs. 32 and 46.
