We investigate the stability of low-friction sliding of nanocrystal with rectangular atomic arrangement on rectangular lattices, for which analytical results can be obtained. We find that several incommensurate periodic orbits exist and are stable against thermal fluctuations and other perturbations. As incommensurate orientations lead to low corrugation, and therefore low friction, such incommensurate periodic orbits are interesting for the study of nanotribology. The analytical results… Expand

It is shown that generalizations towards heterogeneous junctions and non-planar structures provide a route for designing nanoscale systems with unique tribological properties, such as robust superlubricity, and future extension of this method towards nonparallel interfaces, bulk-material junctions, molecular surface diffusion barriers, and dynamic simulations are discussed.

Stability of superlubric sliding on graphite.
It is found that the optimal conditions to achieve superlubric sliding are given by large flakes, low temperature, and low loads, as well as scanning velocities higher than those used in AFM experiments. Expand
Frictional duality observed during nanoparticle sliding.
While some particles show finite friction increasing linearly with the interface areas of up to 310 000 nm(2), other particles assume a state of frictionless sliding, suggesting a link between the degree of surface contamination and the occurrence of this duality. Expand

This work has used the friction force microscope to measure the friction of nanoparticles sliding over flat surfaces, thereby enabling a much larger range of material combinations and interface contact areas to be studied and offering new insight into the atomistic concepts of friction. Expand
Superlubricity of graphite.
By measuring atomic-scale friction as a function of the rotational angle between two contacting bodies, it is shown that the origin of the ultralow friction of graphite lies in the incommensurability between rotated graphite layers. Expand
Onset of sliding friction in incommensurate systems
The onset of friction is due to a novel type of dissipative parametric resonances, involving several resonant phonons which are driven by the (dissipationless) coupling of the center of mass motion to the phonons with the wave vector related to the modulating potential. Expand
Spatially quantized friction with a lattice periodicity
Abstract Using a two-dimensional frictional force microscope (2D-FFM), we investigated the two-dimensional nature of spatially quantized friction with a lattice periodicity on an atomic scale. As aExpand
Torque and twist against superlubricity.
It is demonstrated experimentally and theoretically that superlubricity in contacts lubricated by lamellar solids might be eliminated due to torque-induced reorientation coupled to lateral motion. Expand
