Self-powered photodetectors with a broadband response have attracted great attention due to their potential applications in sensing, imaging, communication, and spectroscopy. Specifically, those with the detection wavelength range covering mid-infrared at room temperature are very challenging and highly desired. Here, the photoresponse of self-powered SmB6 photodetectors is demonstrated through the spatially resolved photocurrent mapping. The photocurrent originates from the interface between the SmB6 and Au electrodes due to the charge separation by built-in electric fields at the interface. It exhibits a stable photoresponse over broadband wavelengths ranging from 488 nm to 10.6 mu m at room-temperature. Our results suggest that the chemical vapor deposition grown SmB6 nanowires could be promising candidates for future broadband self-powered detectors and pave the way toward SmB6-based optoelectronic applications.
