Strain and Twist Engineering of Interfacial Thermal Transport in Homo- and Hetero-Interfaces of Graphene and Hexagonal Boron Nitride
Wenwu Jiang, Huasong Qin, Yilun Liu +3
A dramatic difference between the vertical thermal conductance response of homogeneous and heterogeneous graphene/h-BN interfaces to external mechanical perturbations, is predicted…
Observation of robust macroscale structural superlubricity
Minhao Han, Deli Peng, Dinglin Yang +10
Structural superlubricity (SSL) promises nearly frictionless and wearless sliding, but has until now been considered a special and extreme interfacial phenomenon limited to micro-…
Frictional Dissipation and Scaling Laws at van der Waals Interface: The Key Role of Elastic Pinning of Moiré at Edges and Corners
Xiang Gao, Weidong Yan, Wengen Ouyang +3
Van der Waals heterogeneous interfaces are promising candidates for the scaling up of structural superlubricity to meet practical applications. Several factors, however, have been…
Chemifriction and Superlubricity: Friends or Foes?
Penghua Ying, Xiang Gao, Amir Natan +2
The mechanisms underlying chemifriction, i.e. the contribution of interfacial bonding to friction in defected twisted graphene interfaces are revealed using fully atomistic machine…
Emerging chirality and moiré dynamics in twisted layered material heterostructures
Andrea Silva, Xiang Gao, Melisa M. Gianetti +5
Moiré superstructures arising at twisted 2D interfaces have recently attracted the attention of the scientific community due to exotic quantum states and unique mechanical and tri…
