“…3,4 Methods for the synthesis of SWNTs do not produce a monodisperse product, and the large scale purification of SWNTs has been achieved only recently. 5 The cohesion of these molecular crystals occurs through van der Waals interactions and perhaps other effects of electron correlation, [6][7][8][9] and it is widely observed that the individual SWNTs coalesce into rope-like strands. 10 Many properties of condensed SWNTs are now topics of intensive study.…”

Hydrogen adsorption on crystalline ropes of carbon single-walled nanotubes ͑SWNT͒ was found to exceed 8 wt. %, which is the highest capacity of any carbon material. Hydrogen is first adsorbed on the outer surfaces of the crystalline ropes. At pressures higher than about 40 bar at 80 K, however, a phase transition occurs where there is a separation of the individual SWNTs, and hydrogen is physisorbed on their exposed surfaces. The pressure of this phase transition provides a tube-tube cohesive energy for much of the material of 5 meV/C atom. This small cohesive energy is affected strongly by the quality of crystalline order in the ropes.

“…Among all the possible nanostructure materials, carbon nanotubes have attracted much attention since their discovery in 1991, 3 because of their special geometrical and electronic properties. Their electronic and transmission properties have been studied both experimentally [4][5][6][7][8] and theoretically. [9][10][11][12][13] In particular, from the theoretical point of view, the sensitivity of their electronic properties to their geometry makes them truly unique in offering the possibility of studying quantum transport in a very tunable environment.…”

Electronic transport in extended systems: Application to carbon nanotubes

We present an efficient approach to describe the electronic transport properties of extended systems. The method is based on the surface Green's function matching formalism and combines the iterative calculation of transfer matrices with the Landauer formula for the coherent conductance. The scheme is applicable to any general Hamiltonian that can be described within a localized orbital basis. As illustrative examples, we calculate transport properties for various ideal and mechanically deformed carbon nanotubes using realistic orthogonal and nonorthogonal tight-binding models. In particular, we observe that bent carbon nanotubes maintain their basic electrical properties even in the presence of large mechanical deformations.

“…This leads to the important conclusion that the DOS (and hence properties related to it) does not depend on the details of the relative orientations of the tubes. The existence of the pseudogap due to the broken symmetry in the rope makes the conductivity and other transport properties significantly different from those of isolated tubes, even without considering the effect of local disorder in low dimensions 13,14 . The carrier density will increase as the temperature is raised because the DOS increases quickly away from the Fermi level, as shown in Fig.…”
