Registry dependent potential for interfaces of gold with graphitic systems
Wengen Ouyang, Oded Hod, Roberto Guerra
We present a semi-anisotropic interfacial potential (SAIP) designed to classically describe the interaction between gold and two-dimensional (2D) carbon allotropes such as graphene…
Friction of Physisorbed Nanotubes: Rolling or Sliding?
Davide Mandelli, Roberto Guerra
The structure and motion of carbon and h-BN nanotubes (NTs) deposited on graphene is inquired theoretically by simulations based on state-of-the-art interatomic force fields. Resul…
Static friction boost in edge-driven incommensurate contacts
Davide Mandelli, Roberto Guerra, Wengen Ouyang +2
We present a numerical investigation of the size scaling of static friction in incommensurate two dimensional contacts performed for different lateral loading configurations. Resul…
Experimental observation of the Aubry transition in two-dimensional colloidal monolayers
T. Brazda, A. Silva, N. Manini +4
The possibility to achieve entirely frictionless, i.e. superlubric, sliding between solids, holds enormous potential for the operation of mechanical devices. At small length scales…
Ballistic thermophoresis of adsorbates on free-standing graphene
Emanuele Panizon, Roberto Guerra, Erio Tosatti
The textbook thermophoretic force which acts on a body in a fluid is proportional to the local temperature gradient. The same is expected to hold for the macroscopic drift behavior…
Graphene nanoribbons on gold: Understanding superlubricity and edge effects
Lorenzo Gigli, Nicola Manini, Andrea Benassi +3
We address the atomistic nature of the longitudinal static friction against sliding of graphene nanoribbons (GNRs) deposited on gold, a system whose structural and mechanical prope…
