摘要
The results of electronic properties and microstructure investigations in amorphous diamond like carbon films (a-C:H) containing different concentrations of silver impurity are presented. The films were prepared by the combined graphite-silver target sputtering in the atmosphere of argon-hydrogen plasma. By the method of transmission electron microscopy it was established that Ag was embedded in the matrix of a-C:H as isolated spherical shape nanoclusters. The average size of the nanoclusters was grown from 2 to 8 nm when silver concentration was ranged from 1 to 20 at. %, respectively. The resonance optical absorption at similar to 420 nm was revealed in the films. The dependence of films conductivity on Ag content is typical of percolation systems.
