Atomic-scale friction of black phosphorus/degraded Cu substrate: A route to robust superlubricity obtained by the critical load

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

“…This method has been extensively used in theoretical studies focusing on interlayer friction properties. [46][47][48][49][50] The success of Zhong and Tomanek's theory is rooted in its utilization of density functional theory (DFT) calculations. The interaction between the two surfaces at different positions of the slipping processes is calculated via first-principles calculations.…”
