Abstract: An enhanced interference phenomenon in the IR absorbance-wavenumber profiles of ship-shaped carbon nanotubes powder has been observed by attenuated total reflection at room temperature. This room temperature interference phenomenon was considered as possibly originating from an optical resonance effect and that single carbon nanotubes could act as individual Fabry-Perot or Lummer-Gehrcke resonant cavities. It is demonstrated that this interference phenomenon could be an Anderson type localisation phenomenon due to resonant modes in the semi-disordered ship-shaped carbon nanotubes nanopowder which could form a plausible resonant cavity.
