Quantum transport properties of ultrathin silver nanowires
Jijun Zhao, Buia Calin, Jie Han +1
The quantum transport properties of the ultrathin silver nanowires are investigated. For a perfect crystalline nanowire with four atoms per unit cell, three conduction channels are…
Melting behavior of ultrathin titanium nanowires
Baolin Wang, Guanghou Wang, Jijun Zhao
The thermal stability and melting behavior of ultrathin titanium nanowires with multi-shell cylindrical structures are studied using molecular dynamic simulation. The melting tempe…
Binding energies and electronic structures of adsorbed titanium chains on carbon nanotubes
Chih-Kai Yang, Jijun Zhao, Jian Ping Lu
We have studied the binding energies and electronic structures of metal (Ti, Al, Au) chains adsorbed on single-wall carbon nanotubes (SWNT) using first principles methods. Our calc…
Magic structures of helical multi-shell zirconium nanowires
Baolin Wang, Guanghou Wang, Jijun Zhao
The structures of free-standing zirconium nanowires with 0.62.8 nm in diameter are systematically studied by using genetic algorithm simulations with a tight-binding many body p…
Does the melting behavior in ultrathin metallic nanowires begin from the surface ?
Jinlan Wang, Xiaoshuang Chen, Guanghou Wang +3
Surface melting temperature is well-known significantly lower than the bulk melting point. But we find that the interior melting temperature in ultrathin nanowires is lower than th…
