- Strain modulation is a crucial way in engineering nanoscale materials. It is even more important for single photon emitters in layered materials, where strain can create quantum emitters and control their energies. Here we report the localized, charge-enhanced coupling between the charged localized emitters in monolayer tungsten diselenide (WSe2) to the piezoelectric relaxor ferroelectric substrate. In addition to the strain effect, we observe a gigantic polarizability volume with the enhancement factor up to 1010. The enormous polarizability leads to a large Quantum-confined Stark shift under a small variation of electric field, indicating the potential of integrating layered materials with functional substrates for quantum sensing. We further demonstrate the tunable diamagnetic shift and g-factor with strain varying by ~0.05%, which confirms the existence of enhanced interaction between the localized oscillating dipoles and the ferroelectric domains. Our results signify the prospect of charged quantum emitters in layered materials for quantum sciences and technology.
