Outline of Final Research Achievements

Carbon nanocoil is a carbon nanomaterial with solenoid construction. Though, CNCs are shown to be an excellent electromagnetic wave absorption material, the application of CNCs to nano-inductor is not quite advanced yet due to its smallness. I have developed manipulation technique for fixing one CNC on substrate using focused ion beam and measured the electrical resistivity. I obtained the correlation between the coil diameter and resistivity. The resistivity increased with the coil diameter. I compared the resistivity of CNCs with that of graphitized CNCs (GCNCs) which were prepared in argon gas at 2873K. The CNCs with smallest coil diameter had almost the same resistivity with GCNCs, and the resistivity of GCNCs was not changed with their coil diameters. These fundamental experimental results are quite important in order to achieve the observation of the electromagnetic induction phenomena of CNCs.
