Single-photon emitters play a key role in present and emerging quantum technologies. Several recent measurements have established monolayer WSe2 as a promising candidate for a reliable single-photon source. Researchers in Austria have shown that the origin and underlying microscopic processes responsible for this quantum light effect are the subtle interaction of single atomic defects in the material and mechanical strain. Computer simulations show how the electrons are driven to specific places in the material, where they are captured by a defect, lose energy and emit a photon…read more. TECHNICAL ARTICLE
