Abstract

Amorphous hydrogenated carbon films were prepared by plasma assisted CVD method. Their de conductivity was studied as a function of temperature in the range of 300 K to 10 K. films were then subjected to high energy (170 MeV) ion irradiation. After irradiation a marked change was observed in the conductivity and its temperature dependence. The conductivity decreased by 2-3 orders of magnitude and a gap appeared in the electronic structure. UPS studies of the material show a decrease in the \pi states of the electronic density of states spectrum. A change in the C1s peak shape was observed in XPS study of the irradiated carbon film.
