Abstract
A material of carbon nanotubes and diamond bonded together. A method of producing carbon nanotubes and diamond covalently bonded together is disclosed with a substrate on which is deposited nanoparticles of a suitable catalyst on a surface of the substrate. A diamond seeding material is deposited on the surface of the substrate, and then the substrate is exposed to a hydrogen poor plasma for a time sufficient to grow carbon nanotubes and diamond covalently bonded together.
Claims23
A material comprising carbon nanotubes and diamond covalently bonded together.
10-20. (canceled)
A hybrid of carbon nanotubes and diamond made by the method, comprising providing a substrate, depositing nanoparticles of a suitable catalyst on a surface of the substrate, depositing diamond seeding material on the surface of the substrate, and exposing the substrate to a hydrogen poor plasma for a time sufficient to grow a hybrid of carbon nanotubes and diamond.
The hybrid of claim 26, wherein said substrate is Si and/or SiO2, said catalyst is one or more of Fe, Ni and Co, and mixtures or alloys thereof, said diamond seeding material is nanocrystalline diamond powder, and said plasma includes at least about 99% Ar.
A material characterized by its SEMs substantially as shown in FIGS. 5-14.
A combination of intermixed CNTs and supergrains of UNCD.
A film of UNCD having atomically abrupt grain boundaries and CNTs at least some of which extend through said atomically abrupt grain boundaries.
A film of UNCD and CNTs with said CNTs randomly oriented with respect to said UNCD and distributed in a predetermined pattern.
A thin film formed by the simultaneous deposition of UNCD and CNTs on a substrate.
