Abstract

The behavior of composite C/Cu/C film, which is deposited by dc magnetron sputtering and in which the nanosized copper particles are located between two layers of amorphous carbon, is studied during annealing at 600 °C in vacuum. The structural evolution is examined by transmission electron microscopy and electron diffraction. The structure of the composite film is found to be stable in annealing up to 15 h. The diffusion coalescence of copper particles is virtually restricted by the specific micro-structure of carbon matrix.
