Moir Engineering in 2D Materials Beyond Graphene

Abstract

In this project we demonstrated designs and concepts that may be achieved through defect engineering in 2D material layers, enabled by application of stretching and compressive strains as well as rigid body rotations between the 2D layers. We developed accurate computational methods relying on force-field and DFT relaxation of defect structures (in the covalent lattice) with force coupling between the 2D layers to account for VdW commensurability.
