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 integrated nanophotonics (light-based electronics).
Viruses kill millions around the world each year. « In addition to the novel coronavirus, leading viral killers include hepatitis, HIV, HPV, » said Lela Vukovic, Assistant Professor of Chemistry, University of Texas at El Paso.Lire la suite
