Exciton diffusion in monolayer semiconductors with suppressed disorder
Jonas Zipfel, Marvin Kulig, Raül Perea-Causín +8
Tightly bound excitons in monolayer semiconductors represent a versatile platform to study two-dimensional propagation of neutral quasiparticles. Their intrinsic properties, howeve…

Exciton propagation and halo formation in two-dimensional materials
Raul Perea-Causin, Samuel Brem, Roberto Rosati +6
The interplay of optics, dynamics and transport is crucial for the design of novel optoelectronic devices, such as photodetectors and solar cells. In this context, transition metal…

Exciton diffusion and halo effects in monolayer semiconductors
Marvin Kulig, Jonas Zipfel, Philipp Nagler +6
We directly monitor exciton propagation in freestanding and SiO2-supported WS2 monolayers through spatially- and time-resolved micro-photoluminescence under ambient conditions. We…
