Composite Ag/C:H films were deposited using an electromagnetron with A
g target operated in the de unbalanced mode in a working gas mixture o
f n-hexane/Ar. The C:H component of this composite was investigated an
d its polymeric nature revealed. Structure, basic optical and de elect
rical properties are described with the main emphasis on the ageing pr
ocesses. A qualitative explanation is proposed. Copyright (C) 1996 Els
