Strain engineered tuning of hBN towards photonic quantum computing light sources

Abstract

Localized points of strain change the electronic structure of the material (bandgap and exciton binding energy) to emit photons differing in nature than that from the surrounding material, thereby creating single photons. Adjusting the strain leads to tunability in properties, such as the emission spectrum and lifetime of emission, thereby improving efficiency and consistency of single photon emitters.
