Developing versatile systems that can concurrently achieve energy saving and energy generation is critical to accelerate carbon neutrality. However, challenges on designing highly effective, large scale, and multifunctional photonic film hinder the concurrent combination of passive daytime radiative cooling (PDRC) and utilization of sustainable clean energies. Herein, a versatile scalable photonic...
Multispectral complementary detection technologies have made single‐band camouflage materials ineffective, creating strong demand for multispectral compatible camouflage materials. Here, multiscale‐hierarchical metasurfaces (MHM) compatible with large‐area low‐cost fabrication are proposed for the first time to realize multispectral camouflage of dual‐band lasers, infrared and microwave. The MHM consists...
Recently, disordered metasurfaces have attracted considerable interest due to their potential applications in imaging, holography, and wavefront shaping. However, how to emerge long‐range ordered phase distribution in disordered metasurfaces remains an outstanding problem. Here, a general framework is proposed to generate a spatially homogeneous in‐plane phase distribution from a disordered metasurface,...
Bolometric photodetectors have been widely investigated and studied since their delicate applications in military, commercial, public, and academic domains. In article number 1904482, Hailin Peng, Xueao Zhang, Shiqiao Qin, and co‐workers report that a Bi2O2Se‐based bolometer shows a high temperature coefficient of resistance (−1.6% K−1), high bolometric coefficient (−31 nA K−1) and high bolometric...
Bi2O2Se is emerging as a photosensitive functional material for optoelectronics, and its photodetection mechanism is mostly considered to be a photoconductive regime in previous reports. Here, the bolometric effect is discovered in Bi2O2Se photodetectors. The coexistence of photoconductive effect and bolometric effect is generally observed in multiwavelength photoresponse measurements and then confirmed...
