Strain-induced single-photon emitters in layered semiconductors — •Rudolf Bratschitsch — Westfälische Wilhelms-Universität Münster, Münster, Deutschland

Single-photon sources are important building blocks for quantum information technology. Emitters based on solid-state systems provide a viable route for their integration in photonic devices. Recently, we have found single-photon emitters in the atomically thin semiconductor WSe2 [1]. We show that the quantum light sources are strain-induced and demonstrate deterministic positioning of the emitters on the nanoscale [2]. Finally, we present single-photon emission from the layered semiconductor GaSe and provide evidence that the incorporated non-classical light sources are also strain-induced [3].
