A number of outstanding questions, such as the p‐type nature of most CNTFETs and the effects of gases on their function, can be answered on the basis of the SB model. Finally, we briefly discuss the unique characteristics of the SBs in 1D systems on the basis of studies on carbon and boron nitride nanotubes.","PeriodicalId":196292,"journal":{"name":"Structural and Electronic Properties of Molecular Nanostructures.

We show that transport on the composite films close to the percolation threshold yields information about the nanoscopic properties. Transport occurs through 3D hopping of localized carriers in presence of a soft Coulomb gap. This gap likely originates from the charging energy of the isolated tubes. Its magnitude decreases by increasing the nanotubes content because of the partial screening due to neighbouring tubes. Large non linearities are also observed in the current‐voltage characteristics. They come from electric heating of the conduction gas of metallic tubes, the transport mechanism being preserved. The electrical temperature concept allows us to describe all these transport properties within a unique comprehensive model.","PeriodicalId":196292,"journal":{"name":"Structural and Electronic Properties of Molecular Nanostructures.

The diameter distribution was determined to be 0.8 – 1.2 nm from the spectral positioning of the Radial Breathing Modes. The diameter distribution is consistent with that determined by NIR absorption spectroscopy. At all excitation energies the profile of the G‐line (≈ 1580cm−1) indicates a predominance of semiconducting tubes although at 2.4 eV there is some indication of some contribution from metallic tubes. In all cases the anti Stokes line was weak and the Stokes/anti Stokes ratio was at least an order of magnitude indicating at most weak resonance enhancement in either.","PeriodicalId":196292,"journal":{"name":"Structural and Electronic Properties of Molecular Nanostructures.
