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.
