"KAUST and KACST have come up with a novel way to fill the “green-yellow gap” typically seen in white-LED implementations based on multiple phosphors."
"Their paper describes a nanowire-based LED emitting at 588nm, grown on a low-cost, CMOS-foundry-compatible Ti-thin-film/Si substrate platform. A dense layer of nanowires is grown, reaching a surface density of 9x109 cm−2, with a fill factor of 88%."
