Researchers use a silver sawtooth nanoslit array to produce valley-coherent photoluminescence

Researchers from the University of Groningen managed to produce valley-coherent photoluminescence at room temperatures - by using a silver sawatooth nanoslit array in two-dimensional tungsten disulfide flakes.

So-called "coherent light" can be used to store or transfer information in quantum electronics, and the researchers say that their plasmon-exciton hybrid device model may be promising for future integrated nanophotonics applications.
