| Abstract | |
Strain engineering is a powerful tool for generating single-photon emitters in monolayer (ML) transition metal dichalcogenides. Here, we report on a simple method for generating sharp emission lines (linewidths approximate to 150-500 mu eV) in a monolayer (ML) WSe2 on nano-roughness regions of Tb3+-borogermanate glasses. We performed a polarization-resolved magneto-luminescence study in WSe2/glass at low temperature. Remarkably, we observed several stable and linearly polarized doublet emission peaks in strained regions that are associated with a fine structure splitting due to the anisotropic electron-hole exchange interaction with g-factors of similar to 8.4-9.8. Our results indicate that strain engineering on glass substrates is a promising tool for generating quantum dot-like emitters in ML WSe2 for possible integration with photonics systems for quantum information technology.
