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).
Energy harvesting, a technology to transform small quantities of naturally occurring energy (e.g. light, heat and vibration) into electricity, is gaining attention as a method to power the Internet of Things (IoT) devices.Lire la suite
