Abstract
Kinetically favorable regions are determined for the production of film carbon materials of different allotropic modifications in the microwave plasma of the low-pressure ethanol vapor. Self-organization effects and polymorphic transformations caused by kinetic factors are detected. These phenomena are used to design a low-temperature technology of diamond-graphite and diamond-hydrocarbon nanocomposite materials with controlled surface concentrations and sizes of vertically bonded nanodiamond clusters from 4–5 to 100 nm in size located in a heterogeneous matrix. The influence of the technological parameters of the production of diamond-graphite nanocomposite film materials on their field-emission properties is determined. The emission properties are improved due to a change in the electrophysical properties of the material that is induced by an increase in the role of surface states on the strongly developed surface and by a decrease in the diamond micro-crystallite size in the heterogeneous hydrocarbon matrix.
