Abstract

An improved non-sticking diamond-like nanocomposition includes networks of a-C:H and a-Si:O, wherein the H-concentration is between 85% and 125% of the C-concentration. The composition includes preferably 25 to 35 at % of C, 30 to 40 at % of H, 25 to 30 at % of Si, and 10 to 15 at % of O.
