They performed EBIE of ultra nanocrystalline diamond as well as numerical simulations to study this effect and demonstrated that the rate is limited by the number of active sites available for etching. In the field of sub-10 nm

An AFM-based study on the nanoscale wear of diamond-like carbon against and ultra-nanocrystalline diamond showed that the surface wear increases the size of the contact by gradually removing atoms at discrete sites and is a thermally activated stress-assisted process [79].
