Flat-band quantum materials empowering self-adapted ultrabroadband detectors.

ABSTRACT: Blackbody-sensitive room-temperature photodetectors with ultrabroadband response from the short to very long-wave infrared (VLWIR) range are highly desirable for optical communication, industrial gas leakage detection, night vision, and atmosphere surveillance. Although two-dimensional (2D) semiconductors with narrow bandgaps have shown promise in uncooled short and mid-wave infrared (SWIR and MWIR) detection, achieving blackbody responses extending to long-wave infrared (LWIR) or even the VLWIR region at room temperature remains a challenge. Here, we report a bioinspired room-temperature blackbody-sensitive self-adapted ultrabroadband detector utilizing the 2D flat-band quantum material Nb₃I₈, engineered through an electronic and phononic band strategy.
