Bending strain-driven modification of surface reconstructions: Au(111)
U. Tartaglino, E. Tosatti, D. Passerone +1
Strain can affect the morphology of a crystal surface, and cause modifications of its reconstruction even when weak, as in the case of mechanical bending. We carried out calculatio…

Bent surface free energy differences from simulation
U. Tartaglino, D. Passerone, E. Tosatti +1
We present a calculation of the change of free energy of a solid surface upon bending of the solid. It is based on extracting the surface stress through a molecular dynamics simula…

Realistic simulations of Au(100): Grand Canonical Monte Carlo and Molecular Dynamics
D. Passerone, F. Ercolessi, F. Celestini +1
The large surface density changes associated with the (100) noble metals surface hex-reconstruction suggest the use of non-particle conserving simulation methods. We present an exa…
