Saga University in Japan has reported work towards white LED (WLEDs) based on rare-earth -doped gallium oxide (Ga2O3). The researchers adopted a vertical integration strategy with Ga2O3 layers doped with thulium, europium, and erbium grown on top of one other. This vertical strategy leads to more compact devices without compromising crystal quality; the team say “films…
