The uniqueness of the properties of silicon-carbon and silicon-metalcarbon films, representatives of the nanocrystalline and amorphous classes of carbon allotropes, has led to a wide range of areas of their possible application. In this work, the analysis of the dynamics of development of technologies for obtaining and expanding the areas of application of silicon-carbon and silicon-metal-carbon films has been conducted. Thus, the elasticity, mechanical strength (1500–3000 kg/mm2) and chemical resistance of the films ensured the effectiveness of their application as passivating coatings. Thermal conductivity and high emissivity (0.8), high modulus of elasticity (9∙1011 N/m2), high resistivity of silicon-carbon films (105–108 Ohm∙cm) and their transparency for electromagnetic radiation (up to frequencies of several tens of gigahertz) allow their application for broadband RF devices as moving elements (beams, bridges, membranes) of MEMS switches and varactors. Thermal resistance (up to 600 °C, in an open system), sufficiently high electrical conductivity (resistivity ~ 10–5 Ohm∙cm) and high emissivity of the films make it possible to form broadband heating-type radiators based on silicon-metal-carbon films, with an emission spectrum (depending on film temperature) in the range of 2–14 μm. Phase transformations of an amorphous silicon-carbon film into a graphene film, carried out by high-temperature annealing in vacuum over a catalyst, allows the formation on its basis of control electrodes with low “grid” current losses (no more than 5 %) in vacuum emission devices of power microwave electronics, as well as the functional layer of a multilayer heterostructure of a field emission medium for cold mobile cathode-grid units. The revealed effect of self-modulation of the phase and elemental composition of a silicon-metalcarbon film in the direction of growth is of not only applied but also fundamental interest.
