Полученные плазменно-химическим осаждением a-C : ND покрытия: взаимосвязь эмиссионных свойств и фазового состава

The coatings comprised of the nanodiamond-based and amorphous-carbon-based phases (a-C:ND coatings) are investigated. a-C:ND were synthesized by chemical vapor deposition in arc discharge plasma (by deposition) at various concentrations Ar/H2/CH4. Raman spectroscopy showed that, apart from diamond substructure, studied contain polyene-based phases, while phase is passivated hydrogen to different degrees. interplay between parameters materials' structure analysed. It was shown that ordering amorphous substructure formation boundaries affect electron transport secondary emission properties. subject investigation true spectra for analysis nanostructured carbon materials change polyene fraction samples leads variation ratio field thermionic emission. influence composition on their properties In particular, effect turn on-field, which value varied 9-18 V/μm range samples,
