However, conventional III-nitride-based dual-band detectors are either limited to UV-visible response or rely on external bias. Here, we report a self-powered UV-NIR dual-band photodetector based on a p-PbS-EDT\/n-InGaN heterojunction. Driven by the intrinsic built-in electrical field, the device exhibits distinct zero-bias responsivities of 260.19\u2009mA\u22c5W\n                    <jats:sup>\u22121<\/jats:sup>\n                    (385\u2009nm) and 6.95\u2009mA\u22c5W\n                    <jats:sup>\u22121<\/jats:sup>\n                    (940\u2009nm), with corresponding specific detectivities of 6.38 \u00d7 10\n                    <jats:sup>10<\/jats:sup>\n                    and 1.70 \u00d7 10\n                    <jats:sup>9<\/jats:sup>\n                    Jones, respectively. Systematic electrical transport analysis reveals the response mechanisms of NIR and UV.
