The main objective of this article is to summarize the work performed at the Max-Planck-Institute for Plasma Physics in Garching over the past few years relevant to plasma-surface interaction processes in the system hydrogen and carbon. This includes a short review of the properties of amorphous, hydrogenated carbon layers, further on abbreviated as a-C H, determination of reaction probabilities of reactive species such as atomic hydrogen and methyl radicals, and investigation of the simultaneous interaction of these species and low-energy ions with hydrocarbon surfaces. The reviewed ma-...

In addition to the pure forms of carbon, there are a wide range of carbons of varying crystallinity and hydrogen content that are industrially important. These materials form a continuum from almost pure carbon to those with carbon-hydrogen ratios typical of organic compounds. The materials include amorphous hydrogenated-carbon ( 11.2.4) and a range of industrial carbons ( 11.2.5) such as coal, catalyst supports, catalyst coke and carbon blacks. Finally, metal carbonyl complexes ( 11.2.6) are also considered. 

Amorphous hydrogenated carbon (a-C H) is a material that can be prepared such that it is harder, denser and more resistant to chemical attack than any other solid hydrocarbon. It is transparent across much of the infrared and has good histocompatibility. This combination of properties has lead to applications that include wear and corrosion...
