摘要
The influence of the thickness of a tunnel-thin carbon layer depleted in charge carriers in an enriched noncrystalline carbon matrix on the non-dissipative transport and field emission of electrons is studied. It has been established that the "geometric" increase in the electron self-energy increases the transparency of potential barriers for non-dissipative transport in the heterostructure and at the solid-vacuum interface. It is shown that the introduction of a quantum barrier into the carbon matrix increases the transverse current and rectifying properties of heterostructures, increases the field current density and the steepness of the current-voltage characteristics.
