Magnetoexcitons in van der Waals heterostructure

ORAL

Abstract

In recent studies of spatially indirect excitons (IXs), also known as interlayer excitons, in van der Waals heterostructures (HS) composed of atomically thin layers of transition-metal dichalcogenides (TMD), the long-range IX transport [Zhiwen Zhou et. al., Nature Photonics 18, 823 (2024)] and the long-range IX-mediated spin/valley transport [Zhiwen Zhou et. al., arXiv:2406.04440] were found. In the regime of long-range IX transport and long-range spin/valley transport, we measured and analyzed the IX Zeeman splitting. These studies revealed the g-factors for different IX states and the HS stacking type. We also found the long-range magnetoexciton transport.

*The studies were supported by DOE award DE-FG02-07ER46449, the HS manufacturing was supported by NSF Grant 1905478.
