Mechanical and Tribological Properties of Layered Materials Under High Pressure: Assessing the Importance of Many-Body Dispersion Effects
Wengen Ouyang, Ido Azuri, Davide Mandelli +4
The importance of many-body dispersion effects in layered materials subjected to high external loads is evaluated. State-of-the-art many-body dispersion density functional theory c…
Thermodynamic model of twisted bilayer graphene: Configuration entropy matters
Weidong Yan, Langquan Shui, Wengen Ouyang +1
Twisted bilayer materials have attracted tremendous attention due to their unique and novel properties. Here, we derive a thermodynamic model for twisted bilayer graphene (tBLG) wi…
Load-velocity-temperature relationship in frictional response of microscopic contacts
Wengen Ouyang, Yao Cheng, Ming Ma +1
Frictional properties of interfaces with dynamic chemical bonds have been the subject of intensive experimental investigation and modeling, as it provides important insights into t…
Negative Friction Coefficients in Superlubric Graphite-Hexagonal Boron Nitride Heterojunctions
Davide Mandelli, Wengen Ouyang, Oded Hod +1
Negative friction coefficients, where friction is reduced upon increasing normal load, are predicted for superlubric graphite-hexagonal boron nitride heterojunctions. The origin of…
