Hydrogen-induced Unzipping of Single-Walled Carbon Nanotubes
Henry Scudder, Gang Lu, Nicholas Kioussis
The chemisorption of atomic hydrogen on the single-walled armchair carbon nanotube is studied with ab initio calculations. A single H atom is found to be chemisorbed on both the in…
A nonplanar Peierls-Nabarro model and its applications to dislocation cross-slip
Gang Lu, Vasily V. Bulatov, Nicholas Kioussis
A novel semidiscrete Peierls-Nabarro model is introduced which can be used to study dislocation spreading at more than one slip planes, such as dislocation cross-slip and junctions…
Can vacancies lubricate dislocation motion in aluminum?
Gang Lu, Efthimios Kaxiras
The interaction of vacancy with dislocations in Al is studied using the Semidiscrete Variational Peierls-Nabarro model with ab initio determined gamma surface. For the first time,…
Dislocation constriction and cross-slip in Al and Ag: an ab initio study
Gang Lu, Vasily V. Bulatov, Nicholas Kioussis
A novel model based on the Peierls framework of dislocations is developed. The new theory can deal with a dislocation spreading at more than one slip planes. As an example, we stud…
