Abstract

The use of an Expanding Thermal Plasma (ETP) generated by a cascaded arc for deposition of hydrogen-free carbon nitride material was investigated. For this purpose expts. with an Ar/N2 plasma expanding through a graphite nozzle were performed. The deposition environment was investigated by-emission spectroscopy. The exptl. results give insight in the processes related to the interaction of a nitrogen plasma with a carbon surface and the excitation of the resulting carbon-contg. plasma species. Evidence is found that in an Ar/N2 ETP with a graphite nozzle CN is formed by-the chem. etching of the carbon surface by nitrogen atoms. The excitation of CN(X) species in the expansion is most probably realized by vibrationally excited N2(X,v) states which are formed by reassocn. of nitrogen atoms at the walls. [on SciFinder (R)]
