Intervalley Scattering of Interlayer Excitons in a MoS/MoSe/MoS Heterostructure in High Magnetic Field
Alessandro Surrente, Lukasz Klopotowski, Nan Zhang +9
Degenerate extrema in the energy dispersion of charge carriers in solids, also referred to as valleys, can be regarded as a binary quantum degree of freedom, which can potentially…
Probing the inter-layer exciton physics in a MoS/MoSe/MoS van der Waals heterostructure
M. Baranowski, A. Surrente, L. Klopotowski +9
Stacking atomic monolayers of semiconducting transition metal dichalcogenides (TMDs) has emerged as an effective way to engineer their properties. In principle, the staggered band…
Defect healing and charge transfer mediated valley polarization in MoS/MoSe/MoS trilayer van der Waals heterostructures
Alessandro Surrente, Dumitru Dumcenco, Zhuo Yang +7
Monolayer transition metal dichalcogenides (TMDC) grown by chemical vapor deposition (CVD) are plagued by a significantly lower optical quality compared to exfoliated TMDC. In this…
Dark excitons and the elusive valley polarization in transition metal dichalcogenides
M. Baranowski, A. Surrente, D. K. Maude +7
A rate equation model for the dark and bright excitons kinetics is proposed which explains the wide variation in the observed degree of circular polarization of the PL emission in…
Electroabsorption in MoS
Daniele Vella, Dmitry Ovchinnikov, Nicola Martino +8
To translate electrical into optical signals one uses the modulation of either the refractive index or the absorbance of a material by an electric field. Contemporary electroabsorp…
