Abstract

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.
