Journal ArticleDOI
Speed dependence of atomic stick-slip friction in optimally matched experiments and molecular dynamics simulations.
TL;DR: Comparison of both MD and AFM results with the thermally activated Prandtl-Tomlinson model shows that MD results at the highest speeds are not in the thermologically activated regime, and atomistic details in MD simulations can be reliably used in interpreting AFM data if the MD speeds are slow enough.
Journal ArticleDOI
Molecular dynamics simulation of atomic friction: A review and guide
TL;DR: In this article, the authors present a review of recent progress in molecular dynamics simulation of atomic-scale friction measured by an atomic force microscopy, including materials, surfaces, compliance, contact area, normal load, temperature, and velocity.
Journal ArticleDOI
Role of Wrinkle Height in Friction Variation with Number of Graphene Layers
TL;DR: In this article, molecular dynamics simulations are performed to study the frictional behavior of graphene and it is found that the friction between a diamond tip and graphene decreases with increasing number of graphene layers.
Journal ArticleDOI

TL;DR: In this paper, an innovative surface processing technique, ultrasonic nano-crystal surface modification (UNSM), was used to mitigate the potential for the Ni ions release, which significantly improved surface finish and decrease surface porosity.
Journal ArticleDOI
Atomic roughness enhanced friction on hydrogenated graphene
TL;DR: Atomic friction on hydrogenated graphene is investigated using molecular dynamics simulations and it is found that friction does not monotonically increase with hydrogen coverage on the graphene surface; instead, a maximum friction is observed at a hydrogen coverage between 5 and 10%.
