Carbon films have been prepared by laser-pulse treatment of single crystals of copper, nickel, and cobalt, which have been previously implanted at room temperature with 50 keV carbon ions to a fluence of 1×1018 cm−2. Characterization using Raman scattering, Auger spectroscopy, and transmission electron microscopy showed that the films consisted of amorphous carbon and microcrystalline graphite but not diamond. In addition, an appreciable amount of substrate material was found present embedded in the carbon films.
