Formation of diamond-like carbon films and carbon foam by ultrafast laser ablation

Gamaly, Eugene G; Rode, A. V.; Luther-Davies, B.

Description

The ultra-fast ablation of a graphite target using high repetition rate Nd:YAG lasers allows us to deposit two distinctly different carbonaceous structures, depending on the ambient Ar pressure: a diamond-like carbon film with the surface finish down to atomic level at a pressure below 0.1 Torr, and a fractal C nanofoam with air-like density and diamond-like resistivity at higher pressure. The experimental characterization of vapors and carbonaceous materials produced is presented and...[Show more]
