Conductor-semiconductor heterointerface polarization enhancement for superior electromagnetic wave absorption

doi:10.1016/j.jmst.2025.05.021

Abstract

Abstract: The strategic engineering of conductor-semiconductor heterointerfaces has emerged as a pivotal approach for optimizing microwave attenuation performance. However, challenges persist in comprehensively understanding the synergistic mechanisms between conductor and semiconductor heterointerfaces. This study proposes a novel strategy to enhance polarization relaxation through deliberate heterointerface engineering. A heterostructured composite material consisting of WS₂ nanosheet-encapsulated NiCo hollow spheres embedded in porous carbon fibers (WS₂@NiCo-hc) was successfully fabricated via an integrated approach combining electrospinning, high-temperature annealing, and solvothermal synthesis. Experimental results demonstrate that the constructed semiconductor (WS₂)-conductor (NiCo alloy) heterointerfaces play a pivotal role in synergistic polarization effects. Ultimately, the WS₂@NiCo-hc composite exhibits exceptional electromagnetic wave absorption performance at 2.1 mm thickness, achieving a minimum RL of -64.5 dB with an EAB of 6.24 GHz. This work elucidates the structure-property correlation in heterointerface-mediated polarization dynamics, establishing a universal design principle for high-efficiency microwave absorbers via interfacial polarization engineering.

Key words: Conductor-semiconductor heterointerfaces, Interfacial polarization, Electromagnetic wave absorption
