The phase diagram and hardness of carbon nitrides [PDF]

Scientific Reports, 2015
AbstractNovel superhard materials, especially those with superior thermal and chemical stability, are needed to replace diamond. Carbon nitrides (C-N), which are likely to possess these characteristics and have even been expected to be harder than diamond, are excellent candidates.
