Title: Emergent electronic and excitonic physics in TMD moiré superlattices
Abstract: Heterostructures of 2D materials offer remarkable opportunities for creativity and control in electronic material design. Recently, a unique prospect for 2D stacks has emerged: the ability to tune the twist angle between atomic layers. With a small twist angle or lattice mismatch, the interference of two atomic lattices produces a large periodic pattern, called a moiré superlattice, where the alignment between atoms varies periodically across the system. In this talk, I will focus on moiré superlattices made from semiconducting transition metal dichalcogenide layers. I will introduce three experimental studies highlighting how a simple interference pattern can produce fascinating electronic and optical behavior, including unusual excitons, correlated electronic states, and modified spin transport.
