Ultrafast Optical Control of Exciton Diffusion in WSe/Graphene Heterostructures Revealed by Heterodyne Transient Grating Spectroscopy
Lukas Rieland, Julian Wagner, Robin Bernhardt +8
Using heterodyne transient grating spectroscopy, we observe a significant enhancement of exciton diffusion within a monolayer WSe stacked on top of graphene. We further demonst…

Excitonic Transport and Intervalley Scattering in Exfoliated MoSe2 Monolayer Revealed by Four-Wave-Mixing Transient Grating Spectroscopy
Henning Kuhn, Julian Wagner, Shuangping Han +5
Exciton intervalley scattering, annihilation and relaxation dynamics, and diffusive transport in a monolayer transition metal dichalcogenides are central to the functionality of de…
