Photophysical Characteristics of Boron Vacancy-Derived Defect Centers in Hexagonal Boron Nitride

Single-photon emitter (SPE) sources are important building blocks for photonics-based quantum technologies. Recently, the highly bright and versatile SPEs from the two-dimensional insulator material hexagonal boron nitride (hBN) have attracted significant research interest. However, due to the variability of emitter species and properties, an exact correlation between the underlying atomistic structures and their photophysical properties is...
