Anderson localization of light in AlGaN–GaN nanowires is exploited to fabricate ultraviolet laser arrays with a lasing threshold of only a few tens of amperes per centimetre squared at cryogenic temperature.
A hard superconducting gap can be induced in the semiconductor InAs by proximity with aluminium, paving the way for a range of fundamental studies in mesoscopic superconductivity.
Quantum dots encapsulated in a gold nanoshell provide a hybrid plasmonic–fluorescent emitter with increased stability against high power excitation or drastic changes in the environment.
