Abstract
We investigated the Raman, nuclear magnetic resonance (NMR), and transport characteristics of 13C-enriched single-walled carbon nanotubes (13CNTs). Systematic Raman spectroscopy measurements show that the 13C content of 13CNT can be controlled by the 13C source. Full width at half maximum of Raman spectra show a broad peak around 50% of 13C while G/D ratio remains almost constant. 13C NMR measurements indicate that the spin-lattice relaxation consists of two mechanisms and spin-spin relaxation time is of order of sub-millisecond. In transport measurement, we demonstrate that 13CNT shows quantum-dot features at low temperatures.
