Morphological features of diamond films depending on substrate temperatures via a low pressure polymer precursor process in a hot filament reactor

Diamond films were synthesized at low pressure using phenylcarbyne polymer as a precursor in a hot filament reactor. The morphological features of diamond films at different substrate temperatures were investigated by scanning electron microscopy (SEM). Various diamonds, such as microcrystals, flake-like crystals and whiskers were observed. The variation mainly depends on the substrate temperature.
