Abstract

Similarly to graphite, atomically thin graphene films are known to be extremely flexible, exhibit a large in-plane stiffness (~1TPa), and be quite soft in the direction perpendicular to the graphene layers (~30 GPa). However, contrary to expectations, we found that at room temperature under pressure an epitaxial graphene film composed of buffer layer plus one graphene layer on SiC(0001) behaves at the nanoscale as a diamond-hard coating, which we named diamene. This ultra-thin and ultra-hard film exhibits exceptional mechanical responses to nano-indentation, equal, or even superior, to those of a CVD diamond film. Here, we review recent advancements in the study of diamene films, towards implementation of diamene coatings in current state-of-the-art mechanical technologies.
