摘要
The evolution of the electronic structure of C films is followed through the independent measurement of their s and p partial 'density of states' (DOS). The interest in such an approach is that the mutual relationship between the two partial DOS is a powerful indicator of the diamond-like or graphite-like character of a given system. It is shown here by this approach that a graphite-like structure is brought about in C films by thermal treatments, while a diamond-like structure is induced by Si addition during the deposition process.
