ABSTRACT:
Methods are provided for suppressing the growth of graphite and other non-diamond carbon species during the low pressure deposition of carbon to form diamond. In one method, the graphite or other non-diamond carbon species is vaporized using incident radiative energy sufficient to vaporize graphite but insufficient to damage the substrate. In another embodiment the graphite or other non-diamond carbon species is selectively photolyzed, such as, by use of laser energy of appropriate wavelength.
