Tribology of two-dimensional materials: From mechanisms to modulating strategies
Abstract Two-dimensional (2D) materials are crystalline materials made of a single or a few
layers of atoms. They have been an active research subject in recent years because of their …

From ultra-low friction to superlubricity state of black phosphorus: Enabled by the critical oxidation and load
Based on the density functional theory (DFT), we investigate the friction properties of
inevitable oxidized black phosphorus (o-BP). o-BP with the weaker interlayer adhesion …

Atomic-scale friction of black phosphorus from first-principles calculations: Insensitivity of friction under the high-load
Abstract The Amontons-Coulomb law shows that friction is proportional to load, which limits
application of materials. Lubricants can, black phosphorus (BP), effectively inhibit the rapid …

Attraction-Induced superlubricity and its detection
A nanoscale friction test using an atomic force microscope (AFM) is modelled as a diatomic
tip in sliding contact with a 2D monolayer supported by a metal substrate. This test is …

Mutual identification between the pressure-induced superlubricity and the image contrast inversion of carbon nanostructures from AFM technology
Previous studies predict pressure-induced superlubricity, but that is still undetermined due to
the absence of a probing technique. Here, we present unprecedented mutual identification …
