Diamond film growth on the carbon films from electrolysis of ethanol

Diamond films have been deposited on carbon films that were deposited from electrolysis of an ethanol on Si by hot-filament chemical vapor deposition system. The nucleation density of the diamond on carbon–Si substrates of about 108–1010 cm−2 has been achieved. The diamond nucleation and morphology mainly depend on the morphology (thickness) of carbon films. It is proposed that the diamond-phase carbon in the carbon film acts as a nucleation site and enhances the diamond nucleation.
