X Ray Absorption Spectroscopy Study of Graphite and Contaminated Single Wall Carbon Nanotubes Using Surface Annealing Treatment

  • We have investigated thd C 1s 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 π* and σ* conduction states has disappeared,confirming that the feature comes from the surface states,ie surface structural distortion and gas absorption,not form the free electron like interlayer states.Moreover,the intensity of π* and σ* 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 argumentaltion by studying the DOS of the different samples of the contaminated single wall carbon nanotubes.
