Abstract
Fullerene functionalized carbon nanotubes -- NanoBuds -- form a novel class of hybrid carbon materials, which possesses many advantageous properties as compared to the pristine components. Here, we report a theoretical study of the electronic transport properties of these compounds. We use both ab initio techniques and tight-binding calculations to illustrate these materials' transmission properties, and give physical arguments to interpret the numerical results. Specifically, above the Fermi energy we find a strong reduction of electron transmission due to localized states in certain regions of the structure while below the Fermi energy all considered structures exhibit a high-transmission energy band with a geometry dependent width.
