van der Waals heterostructures composed of two-dimensional (2D) transition metal dichalcogenides and vdW magnetic materials offer an intriguing platform to functionalize valley excitonic properties in nonmagnetic TMDs. Here, we report magneto photoluminescence (PL) investigations monolayer (ML) MoSe2 on the layered A-type antiferromagnetic (AFM) semiconductor CrSBr under different field orientations. Our results reveal a clear influence order optical MoSe2, such as anomalous...
We have investigated the optical and magneto-optical properties of monolayer (ML) WSe2 on flakes β-Ga2O3 under high magnetic fields. Remarkably, sharp emission peaks were observed associated with localized excitons related to point defects. A detailed study low-temperature photoluminescence (PL) magneto-PL perpendicular field up 9 T was carried out. Several shown valley g-factors values close −4, which is an unusual result for in WSe2. Furthermore, some PL higher g-factor ≈−7 ≈−12,...
Monolayer transition metal dichalcogenides (TMDs) have emerged as promising materials to generate single-photon emitters (SPEs). While there are several previous reports in the literature about TMD-based SPEs, precise nature of excitonic states involved them is still under debate. Here, we use magneto-optical techniques in-plane and out-of-plane magnetic fields investigate SPEs WSe
