Single-photon emitters in hBN — •Johann Preuß, Osvaldo del Pozo-Zamudio, Robert Schmidt, Philipp Tonndorf, Johannes Kern, Steffen Michaelis de Vasconcellos, and Rudolf Bratschitsch — Physikalisches Institut und Center for Nanotechnology, Westfälische Wilhelms-Universität Münster, Deutschland

Single photon emitters (SPEs) have gained increased attention due to their application in quantum technologies, such as quantum computation and communication. Solid-state SPEs are promising due to their high stability and scalability in addition to the excellent optical properties. Recently, the 2D semiconductors WSe2 and WS2 have been shown to host SPEs [1,2,3]. Hexagonal boron nitride (hBN), a van der Waals insulator, exhibits ultrabright and narrowband single photon emission also at room temperature [4]. We investigate the optical properties of single localized emitters in hBN using photoluminescence spectroscopy.
