Ballistic transport of excitons in van der Waals heterostructure

Oral-In-person

Abstract

We studied transport kinetics of spatially indirect excitons (IXs), also known as interlayer excitons, in van der Waals heterostructure composed of atomically thin layers of transition-metal dichalcogenides. We found long-range ballistic transport of IXs. Describing this transport as diffusive gives the diffusivity orders of magnitude higher than for regular diffusive exciton transport in van der Waals heterostructures.
