Catalytic growth of ultralong graphene nanoribbons on insulating substrates
Bosai Lyu, Jiajun Chen, Shuo Lou +22
Graphene nanoribbons (GNRs) with widths of a few nanometres are promising candidates for future nano-electronic applications due to their structurally tunable bandgaps, ultrahigh c…
Registry dependent potential for interfaces of gold with graphitic systems
Wengen Ouyang, Oded Hod, Roberto Guerra
We present a semi-anisotropic interfacial potential (SAIP) designed to classically describe the interaction between gold and two-dimensional (2D) carbon allotropes such as graphene…
Parity-Dependent Moiré Superlattices in Graphene/h-BN Heterostructures: A Route to Mechanomutable Metamaterials
Wengen Ouyang, Oded Hod, Michael Urbakh
The superlattice of alternating graphene/h-BN few-layered heterostructures is found to exhibit strong dependence on the parity of the number of layers within the stack. Odd-parity…
Sliding Over Graphene Grain Boundaries: A Step Towards Macroscale Superlubricity
Xiang Gao, Wengen Ouyang, Oded Hod +1
In light of the race towards macroscale superlubricity of graphitic contacts, the effect of grain boundaries on their frictional properties becomes of central importance. Here, we…
Controllable Thermal Conductivity in Twisted Homogeneous Interfaces of Graphene and Hexagonal Boron Nitride
Wengen Ouyang, Huasong Qin, Michael Urbakh +1
Thermal conductivity of homogeneous twisted stacks of graphite is found to strongly depend on the misfit angle. The underlying mechanism relies on the angle dependence of phonon-ph…
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…
