摘要

Single photon emitters localized in atomically thin materials have begun to receive much attention from the solid-state quantum optics and quantum photonics communities. In this work we study the quantum emitters present in single layer tungsten diselinde and perform polarization resolved photoluminescence measuements in order to understand the electronic structure of the confined excitons. The emitters are embedded in a van der Waals heterostructure-based diode where quantum confined Stark shift from the excitons is observed. Moreover, we have also demonstrated tunable valley polarization of the confined excitons as a function of the applied electric field.
