✦ Synopsis

A Raman scattering image of a single-wall carbon nanotube (SWCNT) is further analyzed using SIMPLISM and moving-window two-dimensional auto-correlation spectroscopy (MW2DACS). The G band from the SWCNT (obtained from SIMPLISMA) is composed of Breit-Wigner-Fano and Lorentzian peak profiles. The SWCNT is identified as metallic from the broad Breit-Wigner-Fano peak shape. MW2DACS is successfully applied to the image with an enhancement in spatial resolution from 350 nm (image filtering using SWCNT G band) to 200 nm.
