摘要

下一代电磁波（EMW）吸收器的发展需要界面设计的转变。采用分层功函数编程，提出了一种调整界面极化动力学的方法。该方法利用多梯度功函数有效地引导载流子迁移和极化，从而增强交变电磁场下的能量耗散。在这里，我们构建了具有集成梯度界面的1T/2H-MoS2/PPy/VS2复合吸收体。该复合材料在2.3 mm处的强吸收（RLmin）为-58.59 dB，在2.5 mm处的有效吸收带宽（EAB）为7.44 GHz，显示出宽带吸收的改善。雷达横截面（RCS）模拟显示，在0°时EMW损耗为-7.2 dB m2，突出了其隐身和通信应用的潜力。本研究介绍了分层功函数编程作为EMW吸收器设计的一种有前途的策略，有助于材料性能和功能的进步。

Hierarchical work function programming for optimizing interfacial polarization in electromagnetic wave absorber

The development of next-generation electromagnetic wave (EMW) absorbers requires a shift in interface design. By employing hierarchical work function programming, we propose an approach to tune interfacial polarization dynamics. This method utilizes multi-gradient work functions to guide carrier migration and polarization effectively, thereby enhancing energy dissipation under alternating electromagnetic fields. Here, we constructed a 1T/2H-MoS₂/PPy/VS₂ composite absorber with integrated gradient interfaces. The composite achieved a powerful absorption (RL_min) of -58.59 dB at 2.3 mm, and an effective absorption bandwidth (EAB) of 7.44 GHz at 2.5 mm, demonstrating improved broadband absorption. Radar cross-section (RCS) simulations show an EMW loss of -7.2 dB m² at 0°, highlighting its potential for stealth and communication applications. This study introduces hierarchical work function programming as a promising strategy in EMW absorber design, contributing to advancements in material performance and functionality.
