Ballistic transport of excitons in van der Waals heterostructure

ORAL

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.

*The studies were supported by DOE award DE-FG02-07ER46449, the heterostructure manufacturing and data analysis were supported by NSF Grants 1905478 and 2516006.
