摘要

This article investigates the electrophysical properties of thin metal-carbon films containing one-dimensional carbon structures stabilized by gold nanoparticles. It is shown that the gold concentration in the film significantly affects conductivity: at high concentrations, metallic charge transport dominates, while at low concentrations, semiconductor-like behavior with a Schottky barrier is observed. A tunneling conductivity model accounting for nanoparticle concentration is developed and validated with an error of up to 10%. Resonance optical pumping induces the generation of free charge carriers, suggesting potential applications in optoelectronics.
