摘要	Uncooled long-wavelength infrared photodetectors based on two-dimensional materials have wide applications, such as remote sensing, missile guide, imaging, and night vision. However, realizing high-performance photodetectors based on 2D materials with high photoresponsivity and fast response speed is still a challenge. Here, we report an ultra-broadband photodetector based on the PdSe2/BP van der Waals heterodiode with a fast response speed. The detection range of the PdSe2/BP heterodiode is covered from visible to long-wave infrared (0.4-10.6 mu m). A high photoresponsivity of 116.0 A/W and a low noise equivalence power of 8.4 x 10(-16) W/Hz(1/2) and D* of 2.05 x 10(9) cm Hz(1/2)/W were demonstrated. Notably, the heterodiode exhibits a very fast response speed with tau(r) = 2.9 and tau(d) = 4.0 mu s. Our results introduced a promising application in broadband and fast photoresponse at weak light intensity.
