Abstract: on measurements of many SWNTs at the single nanotube level [3].The electronic properties of SWNTs are remarkable insofar as they can be either metallic (when m−n = 3q and q is an integer) or semiconducting (when n−m = 3q±1). Raman spectroscopy can be used to distinguish between metallic and semiconducting tubes, because of the very different spectral lineshapes observed for metallic and semiconducting SWNTs with diameters less than 2 nm [1]. Single Nanotube Raman SpectroscopyThe large density of electronic st…
