Transport suppression in polymer-doped zigzag carbon nanotubes
(2005)
The conductance of zigzag carbon nanotubes in the presence of grafted polymers attached to their walls is investigated. A theoretical study of the dependence of the transport on the nature of the molecule and on the ...
Upper bound for the conductivity of nanotube networks
(2009)
Films composed of nanotube networks have their conductivities regulated by the junction resistances formed between tubes. Conductivity values are enhanced by lower junction resistances but should reach a maximum that is ...
Radial oscillations of local density of states in carbon nanotubes
(2001)
By performing an analytical study of the electronic structure of metallic carbon nanotubes, we show that the
local density of states exhibits well-defined oscillations as a function of the nanotube radius. The periods ...
Geometric Constraints in the Growth of Nanotube Templated Polymer Monolayers
(2004)
We present a simple and general model that describes the ordered assembly of polymer strands on nanotube surfaces. Energetically favorable coiling angles are identified based on geometric constraints that limit the maximum ...
