Graphene-hBN interlayer interactions from quantum Monte Carlo
Kittithat Krongchon, Tawfiqur Rakib, Daniel Palmer +3
The interaction between graphene and hexagonal boron nitride (hBN) plays a pivotal role in determining the electronic and structural properties of graphene-based devices. In this w…
Quantifying superlubricity of bilayer graphene from the mobility of interface dislocations
Md Tusher Ahmed, Moon-ki Choi, Harley T Johnson +1
Van der Waals (vdW) heterostructures subjected to interlayer twists or heterostrains demonstrate structural superlubricity, leading to their potential use as superlubricants in mic…
Registry-dependent potential energy and lattice corrugation of twisted bilayer graphene from quantum Monte Carlo
Kittithat Krongchon, Tawfiqur Rakib, Shivesh Pathak +3
An uncertainty in studying twisted bilayer graphene (TBG) is the minimum energy geometry, which strongly affects the electronic structure. The minimum energy geometry is determined…
An accurate tight binding model for twisted bilayer graphene describes topological flat bands without geometric relaxation
Shivesh Pathak, Tawfiqur Rakib, Run Hou +4
A major hurdle in understanding the phase diagram of twisted bilayer graphene (TBLG) are the roles of lattice relaxation and electronic structure on isolated band flattening near m…
Selection rules of twistronic angles in 2D material flakes via dislocation theory
Shuze Zhu, Emil Annevelink, Pascal Pochet +1
Interlayer rotation angle couples strongly to the electronic states of twisted van der Waals layers. However, not every angle is energetically favorable. Recent experiments on rota…
A topologically-derived dislocation theory for twist and stretch moiré superlattices in bilayer graphene
Emil Annevelink, Harley Johnson, Elif Ertekin
We develop a continuum dislocation description of twist and stretch moire superlattices in 2D material bilayers. The continuum formulation is based on the topological constraints i…
