We study the transport properties of defective single-walled armchair carbon nanotubes (CNTs) on a mesoscopic length scale. Monovacancies and divancancies are positioned randomly along the CNT. The calculations are based on a fast, linearly scaling recursive Greenʼs function formalism that allows us to treat large systems quantum-mechanically. The electronic structure of the CNT is described by a density-functional-based tight-binding model. We determine the influence of the defects on the… 

Electronic transport through defective semiconducting carbon nanotubes

We investigate the electronic transport properties of semiconducting (m, n) carbon nanotubes (CNTs) on the mesoscopic length scale with arbitrarily distributed realistic defects. The study is done by

Influence of defect-induced deformations on electron transport in carbon nanotubes

We theoretically investigate the influence of defect-induced long-range deformations in carbon nanotubes on their electronic transport properties. To this end we perform numerical ab-initio

Quantum localization and electronic transport in covalently functionalized carbon nanotubes

A study of the quantum localization induced by functionalization in metallic single walled carbon nanotubes (SWCNT) with circumferences up to 15\,nm and shows that the localization length can decrease down to 20-50\, nm at concentrations of about 1 percent of adsorbates.

Carbon Nanotubes as Etching Masks for the Formation of Polymer Nanostructures.

It is demonstrated that the PMMA nanostructure patterns can be transferred to a different polymer substrate using nanoimprinting, because of the large differences in the Ar ion sputtering yields between CNTs and PMMA.

Tuning the conductance of single-walled carbon nanotubes by ion irradiation in the Anderson localization regime

Anderson localization in carbon nanotubes: defect density and temperature effects.

It is shown that low temperatures, about 15-65 K, are enough to smooth out the fluctuations of the conductance without destroying the exponential dependence of the resistivity as a function of the tube length.
