STRUCTURAL AND OPTICAL PROPERTIES OF ION BEAM SYNTHESIZED CARBONPALLADIUM NANOCOMPOSITE FILMS
Abstract
Carbon-palladium nanocomposite films with a thickness of ~140 nm with a palladium nanoparticle size of up to 2 nm were synthesized by the method of ion sputtering of composite targets. The optical properties of carbon-palladium composite films in the visible spectrum region of were studied. It has been established that the optical absorption of these nanocomposite films is described by the characteristic Tauc dependence. In this case, the presence of palladium nanoparticles leads to a sharp decrease in the optical gap in composite films, which is explained by an increase in the average size of graphene nanoclusters in the carbon matrix.
