ARPES studies of van der Waals heterostructure

ORAL

Abstract

Van der Waals heterostructures are a novel class of ``materials by design" which are formed by stacking different two-dimensional crystals together via van der Waals interaction. The periodic potential by the Moir$\acute{e}$ superlattice can be used as a control knob for tuning the electronic properties of two dimensional materials and can induce various novel quantum phenomena. Here we report direct electronic structure studies the of a model van der Waals heterostructure using angle-resolved photoemission spectroscopy (ARPES).
