Using ab initio calculations, we show that atomic selenium (Se) strongly adsorbs to the outer surface of single wall carbon nanotubes (SWCNTs), converting the semiconductor nanotubes to metallic and enhancing the conductance of the metallic and semimetallic ones. Considering the ease of vaporizing and depositing selenium, due to its volatile nature and low melting point, this system could be potentially viable. Thus, selenium adsorption offers a single process for enhancing the conductance of SWCNTs regardless of their chirality making them a promising candidate for nanoscale interconnects applications.
