The local structure of TiBC and amorphous carbon (a‐C) nanocomposite films (TiBC/a‐C) was correlated with their optical and electrical properties. TiBC/a‐C films with increasing C content were deposited by magnetron co‐sputtering from TiC:TiB2 (60:40) and graphite targets. Chemical composition is determined by electron energy‐loss spectroscopy. Grazing incidence X‐ray diffraction reveals that the...
Highly porous nanocrystalline films of TiO2 sensitized with semiconductor nanocrystals (NCs) are very promising for photovoltaic applications, NCs being more versatile and efficient than organic dyes as sensitizer. In this framework, the visible light absorption of TiO2 can be improved by the superposition of CdS NC absorption band, that is tunable between 2.5 and 5.2 eV. Here, we report on a novel...
