Abstract

In the present work we study electronic transport properties of finite length single-wall carbon nanotubes. A simple model is used to describe the electrodes and the way they are attached to both ends of the CNT. Electronic transport calculations are carried out on three different levels of sophistication. Those are single orbital tight-binding, extended Hückel and density functional theory in combination with Greens function methods. Results are compared and discussed.
