2D (< 10 nm) sp3-C-rich carbon materials, possibly hydrogenated: A review

“…chemical and biological inertness, low electron affinity, high electrical resistance and lack of magnetic response [41] . Therefore, these films are competitive engineering materials for cost-effective hard coating and have been used in widespread applications, primarily as protective coatings in areas such as magnetic [84] and optical storage disks [85][86][87] , optical windows and medical implants, or in micro-electromechanical devices [41] . The sp 3 -C content alone mainly controls the elastic constants, but films with similar sp 3 -C and hydrogen contents but different sp 2 -C arrangements ( e.g.…”
