Abstract:
Measurements of local volt-ampere dependences in carbon diamond-like and graphite-like thin films have been carried out. The analysis of these dependencies allows us to conclude that there is tunneling of charge carriers between conjugated graphite-like clusters through a dielectric layer formed by diamond-like clusters. The structure of a graphite-like cluster, which is a collection of 1 to 3 hexagonal planes shifted relative to each other in positions different from their position in an ideal graphite crystal, allows us to consider their electrophysical properties similar to those of a minimal set of graphene planes. It can be assumed that the revealed features of local volt-ampere dependencies in carbon diamond-like and graphite-like films are related to these electrophysical properties.
