Abstract
Iron nanoparticles were employed to induce the synthesis of diamond on molybdenum, silicon, and quartz substrates. Diamond films were grown using conventional conditions for diamond synthesis by hot filament chemical vapor deposition, except that dispersed iron oxide nanoparticles replaced the seeding. This approach to diamond induction can be combined with dip pen nanolithography for the selective deposition of diamond and diamond patterning while avoiding surface damage associated to diamond-seeding methods.
Claims27
A method of synthesizing diamond comprising:
- depositing iron oxide nanoparticle seeds on a substrate, said iron oxide nanoparticle seeds being capable of carbide formation;
- and directing a stream of gas composition at the seeded substrate under conditions that effect diamond growth.
