摘要：

The field of conducting polymers and molecular carbon nanotubes have gained a lot of attention in the recent years mainly due to the large possibility of technological applications such as light emitting diodes and basic elements for molecular electronics. In this contribution we present an study of the influence of the interaction strengths between single-walled carbon nanotubes and the attached polymers on the electronic properties of these newly formed hybrid structures. By adopting a simple tight-binding model, we investigate the conductance of the functionalized CNs in the presence of a varied number of polymers attached on their walls Random distribution for the set of grafted polymers are considered. The quantum conductance is calculated via the Kubo-Landauer formula, expressed in terms of single-particle Green functions, and we investigate the correlation between the added molecules concentration and the suppression of the electronic transport.
