An Ultraviolet‐to‐NIR Broad Spectral Nanocomposite Photodetector with Gain. Issue 6 (8th April 2014) - Dong, Rui
Abstract A PbS‐based NIR hybrid photodetector with an external quantum efficiency (EQE) above 100% is created by integrating zinc oxide (ZnO) quantum dots (QDs) to induce a photoconductive gain. The dual‐QD hybrid photodetector also shows a tenfold higher responsivity than that of commercial SiC and Si photodetectors in the UV–visible range at room temperature.
