How does CVD diamond compare to DLC?
DLC is an acronym for diamond-like carbon. Other denotations are a-C: H or a-C. In this material, the carbon atoms do not form a crystal lattice but a random (amorphous) network. It is deposited by bombarding a surface with energetic (hydro-)carbon particles. This can be done at room temperature. DLC films exhibit quite a lot of compressive stress which limits the maximum thickness. It is somehow “diamond-like” as it is chemically stable and hard, however, it is clearly no diamond.
