Abstract
A carbon nitride phase with primarily sp(3)-bonded carbon is stabilized in CNx/ZrN superlattice coatings. Rutherford backscattering spectrometry measu rements give a N/C atomic ratio similar to 1.3 for the CNx layers. High-res olution transmission electron microscopy and Z-contrast imaging from the su perlattice show a well-defined layer structure. Raman and near-edge x-ray a bsorption fine structure spectroscopy results reveal the formation of sp(3) -bonded carbon atoms in short-period CNx/ZrN superlattices.
