[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).

[E-Beam] – E-Beam atomic-scale 3D ‘sculpting’ could enable new quantum nanodevices 15 septembre 2020

By varying the energy and dose of tightly-focused electron beams, researchers have demonstrated the ability to both etch away and deposit high-resolution nanoscale patterns on two-dimensional layers of graphene oxide.
