Energy independent, yet higher than 90% internal quantum efficiency (IQE), has been observed in many organic photovoltaics (OPVs). However, its physical origin remains largely unknown and controversial. The hypothesis that the lowest charge-transfer ( . . .

The adsorption of palladium hexafluoracetylacetone (Pd(hfac)2) and nucleation of Pd nanoparticles on TiO2(110) surface were observed using scanning tunneling microscopy (STM). Surface species of Pd(hfac)* and Ti(hfac)* uniformly adsorbed on TiO2(110) . . .
