Silver sawtooth creates valley-coherent light for nanophotonics

Silver sawtooth creates valley-coherent light for nanophotonics Groningen, Netherlands (SPX) Feb 11, 2020
Scientists at the University of Groningen used a silver sawtooth nanoslit array to produce valley-coherent photoluminescence in two-dimensional tungsten disulfide flakes at room temperature. Until now, this could only be achieved at very low temperatures. Coherent light can be used to store or transfer information in quantum electronics. This plasmon-exciton hybrid device is promising for use in Source: NanoDaily.com https://www.spacedaily.com/reports/Silver_sawtooth_creates_valley_coherent_light_for_nanophotonics_999.html
