TL;DR: It is demonstrated that critical issues can be potentially addressed by using nearly defect-free AlGaN tunnel junction core-shell nanowire heterostructures, which exhibit high photoluminescence efficiency in the UV-C band at room temperature and nearly one order of magnitude reduction in the device resistance.

TL;DR: In this article, a light-detection electrochemical cell that is based on vertically aligned p-AlGaN/n-GaN p-n heterojunction nanowires in an electrolyte environment is presented.

TL;DR: In this article, an electrically injected AlGaN nanowire laser operating at 239 nm at room temperature was demonstrated and the spontaneous emission coupling factor was derived to be around 0.012.

TL;DR: In this paper, a new growth paradigm was proposed, wherein a precise control on the optical bandgap of ternary AlGaN nanowires can be achieved by varying the substrate temperature.

TL;DR: In this article, the van de Waals epitaxy of monolayer WSe2 on large area amorphous SiOx substrates was demonstrated for solar water splitting, including extraordinary capacities for efficient light harvesting, water oxidation, and proton reduction.
