Influence of Electrostatic Environment on the Proximity Spin-Orbit Coupling in Graphene on Transition-Metal Dichalcogenides
Bert Jorissen, Bart Partoens, Aires Ferreira +1
We investigate the proximity-induced spin-orbit coupling (SOC) in graphene on transition-metal dichalcogenide (TMD) heterostructures using a tight-binding approach. The tight-bindi…
Comparative Analysis of Tight-Binding models for Transition Metal Dichalcogenides
Bert Jorissen, Lucian Covaci, Bart Partoens
We provide a comprehensive analysis of the prominent tight-binding (TB) models for transition metal dichalcogenides (TMDs) available in the literature. We inspect the construction…
Biaxial strain tuning of exciton energy and polarization in monolayer WS2
G. Kourmoulakis, A. Michail, I. Paradisanos +8
We perform micro-photoluminescence and Raman experiments to examine the impact of biaxial tensile strain on the optical properties of WS2 monolayers. A strong shift on the order of…
Flattening conduction and valence bands for interlayer excitons in a moiré MoS/WSe heterobilayer
Sara Conti, Andrey Chaves, Tribhuwan Pandey +4
We explore the flatness of conduction and valence bands of interlayer excitons in MoS/WSe van der Waals heterobilayers, tuned by interlayer twist angle, pressure, and exter…
Strong gate-tunability of flat bands in bilayer graphene due to moiré encapsulation between hBN monolayers
Robin Smeyers, Lucian Covaci, Milorad V. Milošević
When using hexagonal boron-nitride (hBN) as a substrate for graphene, the resulting moiré pattern creates secondary Dirac points. By encapsulating a multilayer graphene within alig…
Zitterbewegung of moiré excitons in twisted MoS/WSe hetero-bilayers
I. R. Lavor, D. R. da Costa, L. Covaci +3
The moiré pattern observed in stacked non-commensurate crystal lattices, such as hetero-bilayers of transition metal dichalcogenides, produces a periodic modulation of their bandga…
