Synchrotron radiation study of the electronic structure of multiwalled carbon nanotubes

• We present photoelectron (PE) and x-ray absorption spectra (XAS) of macroscopically aligned multiwalled carbon nanotubes. We identify the peaks in the valence PE spectra with regions of high density of states through comparison to calculations for graphite. Finally, we outline and illustrate a simple method for using XAS to determine the average alignment of a nanotube sample.
