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

[Nanophotonics] – Silver sawtooth creates valley-coherent light for nanophotonics
23 February 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).
