Exciton valley depolarization in monolayer transition-metal dichalcogenides
Min Yang, Cedric Robert, Zhengguang Lu +4
The valley degree of freedom is a sought-after quantum number in monolayer transition-metal dichalcogenides. Similar to optical spin orientation in semiconductors, the helicity of…
Filtering the photoluminescence spectra of atomically thin semiconductors with graphene
Etienne Lorchat, Luis E. Parra López, Cédric Robert +6
Atomically thin semiconductors made from transition metal dichalcogenides (TMDs) are model systems for investigations of strong light-matter interactions and applications in nanoph…
Accessing high optical quality of MoS2 monolayers grown by chemical vapor deposition
Shivangi Shree, Antony George, Tibor Lehnert +9
Chemical vapor deposition (CVD) allows growing transition metal dichalcogenides (TMDs) over large surface areas on inexpensive substrates. In this work, we correlate the structural…
Phonon-assisted Photoluminescence from Dark Excitons in Monolayers of Transition Metal Dichalcogenides
Samuel Brem, August Ekman, Dominik Christiansen +7
The photoluminescence (PL) spectrum of transition metal dichalcogenides (TMDs) shows a multitude of emission peaks below the bright exciton line and not all of them have been expla…
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…
Intervalley Polaron in Atomically Thin Transition Metal Dichalcogenides
M. M. Glazov, M. A. Semina, C. Robert +3
We study theoretically intervalley coupling in transition-metal dichalcogenide monolayers due to electron interaction with short-wavelength phonons. We demonstrate that this interv…
