Novel single-bond carbon film and process for the production thereof

摘要

There is provided a novel single-bond carbonic film, matrix of which comprises carbon atoms and which is characterized by having a peak A at 1340+/-20 cm-1 and a peak B at 1580+/-10 cm-1 in Raman spectrum; a value of 9.7 or more for the ratio of IA/IB between the intensity of said peak A(IA) and the intensity of said peak B(IB): and a value in the range of from 30 cm-1 to 110 cm-1 for the half band width of said peak A.
