| Research Abstract |
Carbon nanotube (CNT) has filled with or encapsulated metal as a catalyst. We succeed that development of linear and high aspect ratio Ni filled CNTs by joule heating method. The simple method is that metal mesh grid are held between electrode and Si substrate, and they are electrified to generate joule heat with soaking in ethanol by direct current. Some linear Ni encapsulated CNTs with length : 50-800 nm, diameter : 5-80 nm and aspect ratio : 10-20 were observed. High resolution TEM observation showed that CNT had 3-50 graphene layer. Encapsulated Ni was identified by energy dispersive X-ray spectrum with equipping TEM, and single crystal in face-centered cubic structure by nano beam diffraction. We relocate Ni filled CNTs on needle shape tungsten for new type probe of magnetic force microscope by processing of focused ion beam.
