Carbon-based materials play a major role in today’s science and technology. Among carbon-containing materials such as diamond and graphite, fullerenes, carbon nanotubes, as well as single-layer graphene, diamond-like carbon (DLC) is an interesting amorphous form containing multiple phases including diamond-like sp3 and graphite-like sp2 phases in various proportions. Diamond-Like Carbon coatings have superior properties that can be tailored to meet the specific requirements of electronic applications. DLC films have very strong tolerance for X-ray irradiation, IR transparency, and chemical inertness.
Mechanical properties of DLC such as high hardness and low friction coefficient are now used in numerous industrial applications, including razor blades, magnetic hard discs, critical engine parts, mechanical face seals, scratch-resistant glasses, invasive and implantable medical devices and microelectromechanical systems. In order to expand area of application, metals have been incorporated into DLC, giving way to a new generation of nanocomposite coatings.
This paper will describe properties and applications of diamond-like carbon films with nanocrystalline metal inclusions as a new generation of nanocomposite coatings. The aim is to highlight our achievement in the synthesis, characterization and application of DLC films for II-VI-based radiation detector improvement. We shall present the elaboration of ion-plasma technique for efficient surface processing of CdZnTe and HgCdTe/CdZnTe structures to provide modification of the surface state and passivation of the crystal surface, in particular by DLC films.
