Abstract

We combine {\it ab initio} density functional theory with transport calculations to provide a microscopic basis for distinguishing between `good' and `poor' metal contacts to nanotubes. Comparing Ti and Pd as examples of different contact metals, we trace back the observed superiority of Pd to the nature of the metal-nanotube hybridization. Based on large scale Landauer transport calculations, we ...
