Title: Optical properties of Semiconductor Moiré Crystals

Abstract: A new type of superlattice, known as the moiré superlattice, form when two monolayers of van der Waals materials are stacked to form a heterostructure. While the influence of moiré potential on electronic properties has been extensively studied, its influence on the optical properties of semiconductor heterostructures has just begun to be explored. I will discuss how the moiré potential changes the exciton resonances and diffusion in a manner controllable by the twist angle. These moiré crystals may find exciting applications in quantum information science as a scalable platform for solid-state single photon emitters and spin-photon interfaces.
