Journal ArticleDOI
Diamond-like carbon films with extremely low stress
TL;DR: In this article, the authors report different ways to realize thick diamond-like carbon (DLC) films with stress values lower than 0.5 GPa, and show the heating of the substrates when m contact with the plasma, appears to be one of the most important factors giving rise to the high stress values.
Journal ArticleDOI
Nano indentation measurements on nitrogen incorporated diamond-like carbon coatings
TL;DR: In this article, nanohardness and elastic modulus of diamond-like carbon (N-DLC) films were obtained from 38 to 22 GPa and 462 to 330 GPa, respectively, as the partial pressure of N2 increases from 0 to 76.1%.
Journal ArticleDOI
Effect of high substrate bias and hydrogen and nitrogen incorporation on spectroscopic ellipsometric and atomic force microscopic studies of tetrahedral amorphous carbon films
TL;DR: The influence of substrate bias and hydrogen/nitrogen incorporation on the optical properties and surface morphology of tetrahedral amorphous carbon (ta-C) films, deposited by S bend filtered cathodic vacuum arc (FCVA) process, is reported in this article.
Journal ArticleDOI
X-ray photoelectron spectroscopic study of nitrogen incorporated amorphous carbon films embedded with nanoparticles
TL;DR: In this article, the effect of substrate bias on X-ray photoelectron spectroscopy (XPS) study of nitrogen incorporated amorphous carbon (a-C:N) films embedded with nanoparticles deposited by filtered cathodic jet carbon arc technique is discussed.
