Atomic scale study of superlow friction between hydrogenated diamond surfaces
(American Physical Society, 2004)Strong attractive interaction between two clean diamond (001) slabs turns repulsive upon the hydrogenation of surfaces. This repulsive interaction serves as if a boundary lubricant and prevents the sliding surfaces from ... -
Manipulation of atoms across a surface at room temperature
(Nature Publishing Group, 2000)Since the realization that the tips of scanning probe microscopes can interact with atoms at surfaces, there has been much interest in the possibility of building or modifying nanostructures or molecules directly from ... -
Quantum effects of thermal conductance through atomic chains
(2001)We present a formalism for an atomic scale study of phononic heat transfer. The expression of thermal energy current can be cast in the Landauer form and incorporates the transmission coefficient explicitly. Calculation ... -
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 ... -
Theoretical study of Ga-based nanowires and the interaction of Ga with single-wall carbon nanotubes
(American Physical Society, 2004)Gallium displays physical properties which can make it a potential element to produce metallic nanowires and high-conducting interconnects in nanoelectronics. Using first-principles pseudopotential plane method we showed ...
