• 154 Downloads • Abstract The defect structure of multiwalled carbon nanotubes has been studied by transmission electron microscopy and Raman spectroscopy, with particular attention to the shape and intensity of the defect band D and its overtone D*. Electron-microscopic results demonstrate that multiwalled nanotubes typically have multiple bends. Shiny flowers belinda bely belly gallery hotz pic. The associated short- and long-range disorder influences the Raman spectrum of the nanotubes. The presence of several defect species, differing in scattering probability, results in a stochastic relationship between the intensities of the D*- and D-bands. This relationship is qualitatively interpreted in terms of general mechanisms of elastic/inelastic interactions of π-electrons with phonons and defects.

Hence it may be assumed that the band at 892 cm-1 is, apparently, only typical of VCH units, while the band at 884 cm-~ generally characterizes all VCH units This is supported by the fact that only one band at 887 cm-~ is present in the spectrum of ethylcyclohexane.
