Electrically tuning of single photon emission from a single impurity bound exciton in ZnSe

This work explores the electrically tunable single-photon emission from impurity-bound excitons in zinc selenide (ZnSe), a promising material for quantum photonic applications due to its wide bandgap and stable excitonic properties. By applying an external electric field, we achieve precise modulation of the wavelength of single-photon emission, enabled through the Stark effect. The study employs nanofabricated electrodes to induce electric fields and enhance control over the emission characteristics. Our findings underscore ZnSe's potential as a robust platform for controllable single-photon sources, advancing solid-state approaches in quantum information and photonics.
