Two differentprocedures were used to grow MWCNT films roughly, aligned in the direction normal to the SiO2/Si(111)substrate. Inverse Photoemission Spectroscopy measurements, on these samples, show the existence of resonanceswhich could be traced back to a flat graphene sheet. The unoccupied valence band is fairly similar tothat shown by graphite except by an additional intensity in the vicinity of the Fermi level. This resonance couldbe interpreted both as tubes tips end effects or van Hove singularities in the density of states. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436525 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3B Vol.36 |
