Single‐Photon Emitters: Nanoscale Positioning of Single‐Photon Emitters in Atomically Thin WSe2 (Adv. Mater. 33/2016). Issue 33 (September 2016) - Kern, Johannes
Abstract : Reliable on‐chip quantum optics requires a controlled positioning of single‐photon sources. On page 7101, R. Bratschitsch and co‐workers intentionally create single‐photon emitters in monolayer WSe2 on the nanoscale. The specific strain landscape induced in the monolayer by two single‐crystalline gold nanorods leads to the formation of a localized potential well inside the gap. The image shows an artistic impression of an atomically thin semiconductor folding around gapped gold nanorods with a single‐photon emitter in the gap.
