Formation pathways for single-wall carbon nanotube multiterminal junctions
Using tight-binding as well as classical molecular dynamics we simulate the formation of single-wall carbon nanotube T-, Yand X-junctions via the fusing of two nanotubes. We propose energetically efficient pathways for this process in which all atoms maintain their sp2 arrangements throughout. Recent experimental advances have greatly increased the plausibility of synthesizing multiterminal jun...
متن کاملFormation of Single-Wall Carbon Nanotube Superbundles
Since their discovery in 1993,1,2 carbon single-wall nanotubes (SWNTs) have been of great interest because of their expected novel electronic,3 mechanical,4 and gas adsorption properties.5 Difficulties arise in measuring these various properties because the SWNTs currently available for analyses have very small bundle sizes (1020 nm) and are typically in random orientations. A vital step for th...

متن کاملElectronic transport in metal-soldered carbon-nanotube multiterminal junctions
The structural and conducting properties of single-wall carbon nanotubes SWCNs in soldered configuration is obtained using efficient formalisms based on spin-polarized tight-binding formulation incorporating full consideration of s, p, and d basis sets for carbon and metal atoms. The full structural relaxation of the combined SWCN and metal system is found to be essential for realistic characte...
متن کاملCarbon nanotube "T Junctions": formation pathways and conductivity.
Using tight-binding molecular dynamics we simulate the formation of single wall carbon nanotube T junctions via the fusing of two nanotubes. We propose energetically efficient pathways for this process in which all atoms maintain their sp(2) arrangements throughout. Recent experimental advances have greatly increased the plausibility of synthesizing T junctions as proposed in the simulations. W...
