Abstract

The electrical conductivity and optical constants were measured in amorphous diamond-like carbon doped with copper. The electrical conductivity is analyzed in terms of percolation theory. The observed specific features of the conductivity as a function of copper content are associated with the formation of two different percolation networks. Analysis of measured optical constants of the material indicates that a nanocomposite structure with two types of clusters several nanometers in size is formed in the material.
