Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adom201400023-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A PbS‐based NIR hybrid photodetector</bold> 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. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pghmfn1c23" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
