In this paper we present a theoretical study on single-wall silicon and III-V compound nanotubes. First principles plane wave calculations within density functional theory are used to predict energe...
High Conducting Nanowires Obtained From Uniform Titanium Covered Carbon Nanotubes
carbon nanotube titanium nanowire first principles ab initio
