Localized excitons in Monolayer Transition-Metal Dichalcogenides (ML-TMDs) provide single photons with high brightness and purity. Since both impurities and spatial strain gradients induce quantum emitters (QEs) in ML-TMDs, we fabricated a piezoelectric array of micropillars with ML-WSe2 on top. This structure allows us to induce static and dynamic strain fields to the flake. The QEs nucleation sites are arranged around the pillars, providing control of their position over a few microns. On top of that, by deforming the piezoelectric substrate we can induce external strain fields to the QEs. We demonstrated that this dynamic strain enables QEs energy and brightness tuning. This feature can be explained in a disordered potential landscape scenario, and we confirmed this hypothesis by performing theoretical simulations based on an exciton diffusion model.
