The electronic and chemical structure of carbon nanotubes synthesized by decomposition of acetylene over Fe–Co bimetallic catalysts in different growth conditions, were analyzed by valence band photoelectron spectroscopy and scanning electron microscopy. A clear relationship between the bonding features and the growth condition allowed us to determine the key parameters in terms of temperature, growth...
Nanostructured titanium dioxide (ns-TiO 2 ) films were grown by supersonic cluster beam deposition method. Transmission electron microscopy demonstrated that films are mainly composed by TiO 2 nanocrystals embedded in an amorphous TiO 2 phase while their electronic structure was studied by photoemission spectroscopy. The cluster assembled ns-TiO 2 films are expected...
