Developing clean alternatives to nuclear and fossil energy is essential for the growth of sustainable economies. One of the most attractive alternatives is photovoltaic (PV) technology, using the almost limitless power of the sun to generate electricity.Lire la suite
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).
