[Nanophotonics] – Silver sawtooth creates valley-coherent light for nanophotonics
23 février 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 integrated nanophotonics (light-based electronics).
[Energy Storage] – Scientists learn more about the first hours of a lithium-ion battery’s life
23 février 2020
The first hours of a lithium-ion batteryâs life largely determine just how well it will perform. In those moments, a set of molecules self-assembles into a structure inside the battery that will affect the battery for years to come.
