Spatial coherence of room-temperature monolayer WSe exciton-polaritons in a trap
Hangyong Shan, Lukas Lackner, Bo Han +16
The emergence of spatial and temporal coherence of light emitted from solid-state systems is a fundamental phenomenon, rooting in a plethora of microscopic processes. It is intrins…

Measurement of the Spin-Forbidden Dark Excitons in MoS2 and MoSe2 monolayers
C. Robert, B. Han, P. Kapuscinski +10
Excitons with binding energies of a few hundreds of meV control the optical properties of transition metal dichalcogenide monolayers. Knowledge of the fine structure of these excit…

Control of the Exciton Radiative Lifetime in van der Waals Heterostructures
H. H. Fang, B. Han, C. Robert +9
Optical properties of atomically thin transition metal dichalcogenides are controlled by robust excitons characterized by a very large oscillator strength. Encapsulation of monolay…
