In this paper, a broadband terahertz absorber based on the Dirac‐semimetal AlCuFe is proposed. A classic metal–dielectric–metal (MIM) sandwich structure is adopted, consisting of a periodic AlCuFe pattern on the top, a silica dielectric spacer in the middle, and a gold reflective film at the bottom. When the Fermi leve...

Metal halide perovskite solar cells (PSCs) offer high power-to-weight ratios and superior absorption properties, holding significant promise for space and avionics applications. However, the irradiation stability of PSCs, particularly under fast neutron exposure, remains insufficient. Here, we report a comprehensive st...
This paper proposes an ultra‐broadband terahertz absorber featuring a composite‐patterned monolayer graphene metasurface. By structurally combining a centrally perforated elliptical array with adjacent slotted strips, the absorber achieves a continuous working band from 2.18 to 6.32 THz, with a relative bandwidth of...
