Entangled Telecom Photon Generation using Twisted Van der Waals Crystals
Nidhin Prasannan, Konstantinos Mourzidis, Vishwas Jindal +11
Nanoscale quantum light sources are essential building blocks for integrated quantum photonic systems. Here, we report a wavelength-scale entangled-photon source based on van der W…
Sub-nm range momentum-dependent exciton transfer from a 2D semiconductor to graphene
Aditi Raman Moghe, Delphine Lagarde, Sotirios Papadopoulos +11
Heterostructures made from atomically thin semiconductors (here MoSe) and graphene are uniquely poised to investigate photoinduced charge and energy transfer in the 2D limit. H…
High luminescence efficiency of multi-valley excitonic complexes in heavily doped WSe2 monolayer
Sébastien Roux, Tilly Guyot, Abraao Cefas Torres-Dias +9
Monolayers of group-VI transition-metal dichalcogenides (TMDs) are two-dimensional semiconductors that exhibit exceptionally strong light-matter coupling yet typically suffer from…
Interlayer Coupling and Exciton Dynamics in 2D Hybrid Structures based on an InGaN Quantum Well coupled to a MoSe2 Monolayer
D. Chen, D. Lagarde, L. Hemmen +7
Hybrid structures incorpora1ng both III-nitride and Transi1on Metal Dichalcogenide (TMD) semiconductors have strong applica1on poten1al for light harves1ng and optoelectronics. Her…
Exciton Formation in Two-Dimensional Semiconductors
K. Mourzidis, V. Jindal, M. Glazov +10
The optical properties of atomically thin semiconductors are dominated by excitons, tightly bound electron-hole pairs, which give rise to particularly rich and remarkable physics.…
Spin-valley polarization control in WSe monolayers using photochemical doping
E. Katsipoulaki, K. Mourzidis, V. Jindal +9
We report on the influence of a photochemical doping method on the spin-valley polarization degree () of excitons in WSe monolayers. By varying the carrier density and t…
