Chirality Characterization of Dispersed Single Wall Carbon Nanotubes

Abstract: Raman scattering and optical absorption spectroscopy are used for the chirality characterization of HiPco single wall carbon nanotubes (SWNTs) dispersed in aqueous solution with the surfactant sodium dodecylbenzene sulfonate. Radial breathing mode (RBM) Raman peaks for semiconducting and metallic SWNTs are identified by directly comparing the Raman spectra with the Kataura plot. The SWNT diameters are calculated from these resonant peak positions. Next, a list of (n, m) pairs, yielding the SWNT diameters withi… Show more

“…Resonant Raman scattering (RRS) [ 15 , 16 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 ], Rayleigh scattering [ 44 , 45 , 46 , 47 , 48 ], and photoluminescence (PL) excitation [ 49 , 50 , 51 , 52 , 53 ] have been the mainstream tools for non-destructive chirality characterization, and each method has unique capabilities. Each method uses at least two pieces of information for the unique assignment of chirality [ 37 , 41 , 42 ].…”
