The semiconductor used here is zinc oxide (zincite), which is obtained by taking a strip of zinc and heating it with a blow torch. This creates spots of zinc oxide on the strip, which can then be ...

Haiding Sun, created a vertically integrated micro-scale light-emitting diode (micro-LED ... an AlGaN-based DUV micro-LED array and a zinc oxide (ZnO)-based photodetector (PD) connected via ...
