The influences of atom relaxation on the DFT-calculated friction properties of the h-BN/h-BN and Gr/Gr interfaces

Charge density fluctuation determined the interlayer friction in bilayer MN4 (M = Be, Mg, and Pt)

“…Li et al indicated that surface fluorination increased the friction force of graphene, and this increase was attributed to the concentration of strong local charges at the fluorine sites, leading to heightened fluctuations in interfacial charge density. 13 Furthermore, external or intrinsic factors such as strain, 7,14–16 electric field, 17–20 atomic relaxation, 21 and others also exert vital influence on the friction performance of 2D materials.…”
