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.
