Formation of quantum structures on a single nanotube by modulating hydrogen adsorption
(American Physical Society, 2003)Using first-principles density functional calculations we showed that quantum structures can be generated on a single carbon nanotube by modulating the adsorption of hydrogen atoms. The band gap of the hydrogen-free zone ... -
High-conducting magnetic nanowires obtained from uniform titanium-covered carbon nanotubes
(American Physical Society, 2004)We have shown that a semiconducting single-wall carbon nanotube (SWNT) can be covered uniformly by titanium atoms and form a complex but regular atomic structure. The circular cross section changes to a squarelike form, ... -
Theoretical study of crossed and parallel carbon nanotube junctions and three-dimensional grid structures
(American Physical Society, 2004)This work presents a first-principles study of parallel and crossed junctions of single-wall carbon nanotubes (SWNT). The crossed junctions are modeled by two-dimensional grids of zigzag SWNTs. The atomic and electronic ... -
A theoretical study on silicon and III-V compound nanotubes
(TÜBİTAK, 2005)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 energetics and electronic ...
