AbstractWe have investigated the C Is X ray absorption spectra of graphite and contaminated single wall carbon nanotubes using surface sensitive photoelectron spectroscopy total electron yield mode. After annealing treatment in the ultra high vacuum system, the small feature which has been being ascribed to the so called free electron like interlayer states in between the characteristic pi * and sigma * conduction states has disappeared, confirming that the feature comes from the surface states, ie surface structural distortion and gas absorption, not from the free electron like interlayer states. Moreover, the intensity of pi * and sigma * peaks has changed considerably with this treatment, suggesting that it is necessary to treat the surface of the samples with annealing process in the comparison study of the DOS of the carbon nanotube materials. We have testified this argumentation by studying the DOS of the different samples of the contaminated single wall carbon nanotubes.
