  In the article we introduce the experiment of the photostimulation effect in
the tunneling conductivity of free-standing thin C-Au films. We observe a sharp
increase of the conductivity of hybrid film due to the electromagnetic exciting
at the frequencies which are close to the plasmon resonance of gold
nanoparticles. The use of carbyne threads as a stabilizing matrix makes it
possible to obtain free-standing thin films that demonstrate a good structural
stability. The tunnel current-voltage measurements demonstrate a strong
dependence of the current value on the intensity of green laser radiation used
to photostimulate thin C-Au in area of the measuring experiment.
