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.…
Magnetic imaging under high pressure with a spin-based quantum sensor integrated in a van der Waals heterostructure
