Generating single photons at high temperature remains a major challenge, particularly for group IIIAs and III-P materials widely used in optical communication. Here, we report a high temperature single photon emitter based on a “surface-free” GaAs quantum dot (QD) in a GaAsP nanowire. By using self-catalyzed vapor− liquid−solid growth and simple surface engineering, we can significantly enhance the optical signal from the QDs with a highly polarized photoluminescence at 750 nm....[Show more]
