Abstract The regulation of heteroatoms and heterogeneous interface characteristics has emerged as a promising strategy to enhance electromagnetic wave (EMW) absorption. However, challenges remain in precisely controlling heteroatom doping fully understanding the synergistic mechanisms between interfaces. Here, novel is proposed for enhancing polarization relaxation through optimization. Carbon nanofiber (CNF)‐based Ni–Fe nanocubes decorated with N O are synthesized by pyrolyzing Fe‐based metal–organic frameworks under different atmospheres (NH 3 , H 2 /Ar, Ar). results show that N, play crucial role effect regulating electronic structure diverse structures. Finally, Fe N@Ni Fe/CNFs exhibit excellent EMW absorption at 2.3 mm, minimum reflection loss −56.75 dB, an effective bandwidth 6.7 GHz. Additionally, these materials display remarkable corrosion resistance due their unique fiber network structure. This study highlights optimizing effects, offering valuable insights design advanced heteroatom‐optimized heterointerfaces.

Abstract The modulation of transport properties in ceramic‐based semiconductors can be used to optimize the electromagnetic response mechanism and performance. A semiconductor ceramic foam interlayer wall (SCFW) is designed by a physical vapor deposition method. structural SCFW composed semiconductor‐insulator‐semiconductor layers, incorporating composite system SiC, Al 4.8 Si 1.2 O 9.6 , 2 3 . Moreover, hierarchical network structure controlled pyrolysis‐deposition kinetic process. Electrons holes are transported through heterojunctions between SiC achieving effective charge relaxation. matrix provides lightweight (density 0.967 g cm −3 ), while determines excellent wave (EMW) absorption performance SCFW, with an bandwidth up 14.8 GHz under (minimum reflection loss RL min = −50.6 dB). has been proven exhibit corrosion resistance thermal insulation properties, conductivity 0.025 W m −1 K This study valuable insights into design dielectric property optimization nanocomposites, which leads strong polarization loss, opening new avenues for application EMW absorbers, ceramics.
