Engineering super moiré effects in transition metal dichalcogenides from first-principles

ORAL

Abstract

Transitional metal dichalcogenide (TMD) moiré systems have recently garnered much attention for the plethora of emergent phenomena they showed. Here we perform ab-initio calculations on few-layer twisted TMD. We find that few-layer TMD system can exhibit unique super moiré effects that are remarkably different from twisted bilayer TMD. These effects arise from lattice reconstruction and new stacking patterns, as predicted from calculations and models. Our work establishes twisted few-layer TMD as a new platform to discover novel topology and correlations.
