A novel 1D/1D semiconductor/semiconductor nanocomposite‐based photodetector is fabricated by X. S. Fang and co‐workers on page 2305 from highly crystalline ZnS/ZnO biaxial nanobelts. Optimized performance of the ZnS/ZnO nanobelt photodetector is better than that of pure ZnS or ZnO nanostructures, as it combines UV‐A photoresponsivity, high sensitivity, and a fast response speed. This photodetector is particularly suitable for UV‐A light detection, and its speed enables its potential application in highfrequency light‐wave communications, photoelectronic switches, memory storage devices, and optoelectronic circuits.
