The future of optoelectronics is directed towards small-area light sources, foremost being microLEDs. However, their use has been inhibited so far primarily due to fabrication and integration challenges, which impair efficiency and yield. Recently, bottom-up nanostructures grown using selective area epitaxy have garnered attention as a solution to the aforementioned issues.

Prof. Lan Fu et. al. have used this technique to demonstrate uniform p-i-n core-shell InGaAs/InP nanowire array light emitting diodes. The devices are capable of voltage and geometry-controlled multi-wavelength and high-speed operations. Their publication accentuates the wide capabilities of bottom-up nanostructures to resolve the difficulties of nanoscale optoelectronics.
