TL;DR: In this paper, the authors present a unified theory of the bending of crystalline films that accounts for both elastic effects and crystal defects, and demonstrate that at critical values of the curvature or thickness, there is a second-order phase transition between the undislocated and dislocated film.

TL;DR: In this article, the authors performed molecular dynamics simulations to investigate the self-assembly of a free-standing graphene nano-ribbon (GNR) and found that the kinetic pathway of a GNR is dictated by both the complex energy landscape, which drives the GNR towards a low energy regular conformation, and the formation of locking frustrations, which traps the GNRs at a metastable state with an irregular conformation.

TL;DR: In this paper, atomic simulations of segregation to the ∑5 twist boundary in Ni-Cu alloys have been performed for a wide range of temperature and composition all within the solid solution region of the p...

TL;DR: In this paper, a real space 3D Ginzburg-Landau framework is used to investigate the domain patterns in free-standing ferroelectric nanostructures undergoing cubic to tetragonal transitions.

TL;DR: Optimal NEMS switch performance requires substantial contact conductance and minimal asperity deformation; these results indicate that these goals can be achieved by balancing the quantity of adsorbates and their adhesion to the metal surface.
