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…
Negative Friction Coefficients in Superlubric Graphite-Hexagonal Boron Nitride Heterojunctions
Davide Mandelli, Wengen Ouyang, Oded Hod +1
Negative friction coefficients, where friction is reduced upon increasing normal load, are predicted for superlubric graphite-hexagonal boron nitride heterojunctions. The origin of…
Nanoserpents: Graphene Nanoribbons Motion on Two-Dimensional Hexagonal Materials
Wengen Ouyang, Davide Mandelli, Michael Urbakh +1
We demonstrate snake-like motion of graphene nanoribbons atop graphene and hexagonal boron nitride (h-BN) substrates using fully-atomistic non-equilibrium molecular dynamics simula…
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…
Finite-temperature phase diagram and critical point of the Aubry pinned-sliding transition in a 2D monolayer
Davide Mandelli, Andrea Vanossi, Nicola Manini +1
The Aubry unpinned--pinned transition in the sliding of two incommensurate lattices occurs for increasing mutual interaction strength in one dimension () and is of second order…
Microscopic Friction Emulators
Davide Mandelli, Erio Tosatti
Cold ions sliding across periodic potential patterns formed by lasers elucidate the physics of dry friction between crystals. Experiments with no more than six ions suffice to expl…
