We present a wide-field, high-throughput optical technique for locating solid-state quanutm emitters with <10 nm accuracy, and apply it in the creation of micropillar sources with near-optimal single-photon emission.
We present the efficient generation of coherent single photons based on quantum dots in micropillars. We utilize a scalable lithography scheme leading to quantum dot-micropillar devices with 74% extraction efficiency. Via pulsed strict resonant pumping, we show an indistinguishability of consecutively emitted photons up to 98.5%.
We discuss quantum light emission from solid state single photon sources, either based on single InGaAs quantum dots or trapped excitonic complexes in monolayer WSe2. Embedding InGaAs quantum dots in micropillar cavities, we can simultaneously obtain high purity, bright (up to 75% extraction efficiency) and coherent emission of single photons. Single photon emission in monolayers of transition metal...
A palladium-catalyzed oxidative Heck reaction of fluoro-substituted furans with alkenes was developed to afford tetrasubstituted furans in moderate to good yields.
