摘要：

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 photo-detectors in the UV-visible range at room temperature. © 2014 WILEY-VCH Verlag GmbH & Co.
