Thermal assisted transport of biexcitons in monolayer WSe2
Dorian Béret, Louka Hemmen, Vishwas Jindal +9
Studies of excitonic transport in transition metal dichalcogenide monolayers have attracted increasing interest in recent years in order to develop nano-optoelectronic devices made…
Measurement of Conduction and Valence Bands g-factors in a Transition Metal Dichalcogenide Monolayer
Cedric Robert, Hanan Dery, Lei Ren +9
The electron valley and spin degree of freedom in monolayer transition-metal dichalcogenides can be manipulated in optical and transport measurements performed in magnetic fields.…
Excitons in atomically thin transition metal dichalcogenides
Gang Wang, Alexey Chernikov, Mikhail M. Glazov +4
Atomically thin materials such as graphene and monolayer transition metal dichalcogenides (TMDs) exhibit remarkable physical properties resulting from their reduced dimensionality…
Exciton states in monolayer MoSe2: impact on interband transitions
G. Wang, I. C. Gerber, L. Bouet +7
We combine linear and non-linear optical spectroscopy at 4K with ab initio calculations to study the electronic bandstructure of MoSe2 monolayers. In 1-photon photoluminescence exc…
Exciton dynamics in WSe2 bilayers
G. Wang, X. Marie, L. Bouet +5
We investigate exciton dynamics in 2H-WSe2 bilayers in time-resolved photoluminescence (PL) spectroscopy. Fast PL emission times are recorded for both the direct exciton with $τ_{D…
Fabrication of an InGaAs spin filter by implantation of paramagnetic centers
C. T. Nguyen, A. Balocchi, D. Lagarde +6
We report on the selective creation of spin filltering regions in non-magnetic InGaAs layers by implantation of Ga ions by Focused Ion Beam. We demonstrate by photoluminescence spe…
