Revealing exciton masses and dielectric properties of monolayer semiconductors with high magnetic fields
M. Goryca, J. Li, A. V. Stier +8
In semiconductor physics, many essential optoelectronic material parameters can be experimentally revealed via optical spectroscopy in sufficiently large magnetic fields. For monol…
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…
Exciton states in monolayer MoSe2 and MoTe2 probed by upconversion spectroscopy
B. Han, C. Robert, E. Courtade +10
Transitions metal dichalcogenides (TMDs) are direct semiconductors in the atomic monolayer (ML) limit with fascinating optical and spin-valley properties. The strong optical absorp…
Exciton diffusion in WSe2 monolayers embedded in a van der Waals heterostructure
F. Cadiz, C. Robert, E. Courtade +9
We have combined spatially-resolved steady-state micro-photoluminescence (PL) with time-resolved photoluminescence (TRPL) to investigate the exciton diffusion in a WSe monol…
Identifying optical signatures of momentum-dark excitons in transition metal dichalcogenide monolayers
Jessica Lindlau, Cedric Robert, Victor Funk +12
Transition metal dichalcogenide (TMD) monolayers (MLs) exhibit rich photoluminescence spectra associated with interband optical transitions of direct-gap semiconductors. Upon absor…
Charged excitons in monolayer WSe: experiment and theory
E. Courtade, M. Semina, M. Manca +13
Charged excitons, or X-trions, in monolayer transition metal dichalcogenides have binding energies of several tens of meV. Together with the neutral exciton X they domi…
