DEPOSITION OF CARBON ON DIAMOND SEED CRYSTALS,

Abstract

Experiments were performed to establish the feasibility of growing diamond crystals for potential electronic device application by the deposition of carbon on diamond seed crystals at moderate pressures. Methane at temperatures and pressures on the order of 1050C and 1 mm Hg was used as the source of carbon. Weight increases were consistently observed when pure methane was used as the source of carbon. When the methane was diluted with either hydrogen or helium, the seed crystals decreased in weight. Preliminary investigation of the crystals by Debye-Scherrer X-ray patterns, chemical kinetic studies and visual observation indicate the observed increase in mass is diamond. More definitive studies to verify this conclusion are underway. (Author)
