Two-dimensional (2D) materials are envisaged as ultra-thin solid lubricants for nanomechanical systems. So far, their frictional properties at the nanoscale have been studied by standard friction force microscopy. However, lateral manipulation of nanoparticles is a more suitable method to study the dependence of friction on the crystallography of two contacting surfaces. Still, such experiments are lacking. In this study, we combine atomic force microscopy (AFM) based lateral manipulation and…

Two-dimensional talc as a van der Waals material for solid lubrication at the nanoscale
TLDR
2D talc flakes down to single layer thickness are investigated and revealed to have all properties necessary for efficient lubrication: a low adhesion, hydrophobic nature, and a low friction coefficient.

Gearlike rolling motion mediated by commensurate contact: Carbon nanotubes on HOPG
We report on experiments in which multiwall carbon nanotubes ~CNT’s ! are manipulated with atomic force microscopy ~AFM! on a graphite highly oriented pyrolytic graphite ~HOPG! substrate. We find

Frictional Characteristics of Atomically Thin Sheets
TLDR
Using friction force microscopy, the nanoscale frictional characteristics of atomically thin sheets of graphene, molybdenum disulfide, niobium diselenide, and hexagonal boron nitride are compared to those of their bulk counterparts, suggesting that the trend arises from the thinner sheets’ increased susceptibility to out-of-plane elastic deformation.
Adhesion and friction in mesoscopic graphite contacts
TLDR
It is shown that the friction is fundamentally stochastic in nature and is attributable to the interaction between the incommensurate interface lattices, and bistable all-mechanical memory cell structures and rotational bearings have been realized by exploiting position locking, which is provided solely by the adhesion energy.
Interfacial friction obtained by lateral manipulation of nanoparticles using atomic force microscopy techniques
Nanometer scale metallic particles have been manipulated on an atomically flat graphite surface by atomic force microscopy techniques and quantitative information on interfacial friction was

TLDR
It is proposed that damping via flexural phonons could be a main source for frictional energy dissipation in 2D systems such as graphene.
Friction between van der Waals Solids during Lattice Directed Sliding.
TLDR
Using an AFM probe to oscillate the nanocrystals, it was found that the lateral force required to move them increased linearly with nanocrystal area, suggesting a thermal activation model for the system.

TLDR
The investigations revealed the friction force per unit length for sliding and static friction over a range of nanowire diameters, and it was found that there is a significant difference between the coefficients of the two sliding modes for large wires.
Superlubric sliding of graphene nanoflakes on graphene.

A study of the sliding behavior of graphene nanoflakes (GNFs) on a graphene surface found that the GNFs show facile translational and rotational motions between commensurate initial and final states at temperatures as low as 5 K.
Superlubricity of graphene nanoribbons on gold surfaces
TLDR
The atomically well-defined contact allows us to trace the origin of superlubricity, unraveling the role played by ribbon size and elasticity, as well as by surface reconstruction, and pave the way to the scale-up of superLubricity and thus to the realization of frictionless coatings.
