Abstract: | Diamondlike films are synthesized from gaseous hydrocarbons in a barrier discharge at atmospheric pressure. The films were
investigated using transmission electron microscopy, electron diffraction, and infrared spectroscopy. A technique for determining
the quantitative characteristics of the films (hydrogen content, ratio of different types of carbon-carbon bonds and hydrocarbon
groups) using standard samples is described. The highest-quality films were obtained from methane (ratio of hydrogen to carbon
atoms H/C=1.04, fraction of diamondlike to graphitelike bonds sp
3: sp
2=100%: 0%) and from a mixture of acetylene and hydrogen in the ratio 1:19 (H/C=0.73, sp
3: sp
2=68%: 32%).
