Graphitization of synthetic diamond by 193 nm laser light: Comparison of 12C-enriched diamonds with those of natural isotopic composition
Abstract
Polished surfaces of diamonds of natural isotopic composition are transformed to graphite upon irradiation by ArF excimer laser light. The surface of a similar diamond made of enriched 12C is not. A possible explanation involves a competition between graphitization and ablation in which the former is more strongly affected by the recently determined higher thermal diffusivity of 12C diamond.
