Abstract

Carbon nanotubes containing substitutionally “doped” nitrogen were synthesized using injection chemical vapor deposition methods. X-ray photoelectron spectroscopy comparisons between materials grown with different nitrogen sources suggest that the nitrogen content of the nanotubes has little correlation with the total nitrogen content of the “dopant” gas. Tunneling microscopy and spectroscopy do, however, confirm that drastic distortions occur within the graphene lattice as the nitrogen is substituted. Further, donor states are clearly identifiable within the density of electronic states.
