Non-linear diffusion of negatively charged excitons in WSe2 monolayer
D. Beret, L. Ren, C. Robert +10
We investigate the diffusion process of negatively charged excitons (trions) in WSe2 transition metal dichalcogenide monolayer. We measure time-resolved photoluminescence spatial p…
One pot chemical vapor deposition of high optical quality large area monolayer Janus transition metal dichalcogenides
Ziyang Gan, Ioannis Paradisanos, Ana Estrada-Real +13
We report one-pot chemical vapor deposition (CVD) growth of large-area Janus SeMoS monolayers, with the asymmetric top (Se) and bottom (S) chalcogen atomic planes with respect to t…
Exciton spectroscopy and diffusion in MoSe2-WSe2 lateral heterostructures encapsulated in hexagonal boron nitride
Dorian Beret, Ioannis Paradisanos, Ziyang Gan +17
Chemical vapor deposition (CVD) allows lateral edge epitaxy of transition metal dichalcogenide heterostructures with potential applications in optoelectronics. Critical for carrier…
Stacking-dependent exciton multiplicity in WSe bilayers
Zhijie Li, Jonathan Förste, Kenji Watanabe +6
Twisted layers of atomically thin two-dimensional materials realize a broad range of novel quantum materials with engineered optical and transport phenomena arising from spin and v…
Spin dependent charge transfer in MoSe2/hBN/Ni hybrid structures
H. Tornatzky, C. Robert, P. Renucci +10
We present magneto-photoluminescence measurements in a hybrid 2D semiconductor/ferromagnetic structure consisting of MoSe2/hBN/Ni. When the Nickel layer is magnetized, we observe c…
Relaxation and darkening of excitonic complexes in electrostatically-doped monolayer semiconductors: Roles of exciton-electron and trion-electron interactions
Min Yang, Lei Ren, Cedric Robert +5
We present photoluminescence measurements in monolayer WSe, which point to the importance of the interaction between charged particles and excitonic complexes. The theoretical…
