Abstract The exploration of novel multivariate heterostructures has emerged as a pivotal strategy for developing high-performance electromagnetic wave (EMW) absorption materials. However, the loss mechanism in traditional is relatively simple, guided by empirical observations, and not monotonous. In this work, we presented semiconductor–semiconductor–metal heterostructure system, Mo–MXene/Mo–metal sulfides (metal = Sn, Fe, Mn, Co, Ni, Zn, Cu), including semiconductor junctions Mott–Schottky junctions. By skillfully combining these distinct functional components (Mo–MXene, MoS 2 , metal sulfides), can engineer multiple heterogeneous interface with superior capabilities, broad effective bandwidths, ultrathin matching thickness. successful establishment gives rise to built-in electric field that intensifies electron transfer, confirmed density theory, which collaborates dielectric polarization mechanisms substantially amplify EMW absorption. We detailed synthesis series featuring both semiconductor–semiconductor semiconductor–metal interfaces. achievements were most pronounced Mo–MXene/Mo–Sn sulfide, achieved remarkable reflection values − 70.6 dB at thickness only 1.885 mm. Radar cross-section calculations indicate MXene/Mo–metal have tremendous potential practical military stealth technology. This work marks departure from conventional component design limitations presents pathway creation advanced MXene-based composites potent capabilities.

Abstract Construction of built‐in electric field (BIEF) in nanohybrids has been demonstrated as an efficacious strategy to boost the dielectric loss by facilitating oriented transfer and transition charges, thus optimizing electromagnetic wave absorption property. However, specific influence BIEF on interface polarization needs explore thoroughly strength should be further augmented. Herein, several systems incorporated Mott–Schottky heterojunctions hollow structures are designed constructed, where bimetallic zeolitic imidazolate framework employed derive Cu‐ZnO heterojunctions, hierarchical enriched introducing structure reduced graphene oxide. The well‐established “double” verified theoretical calculation engineering can regulate conductivity, enhance relaxation effectively. Especially, there always coexisted both enhanced charge separation reversed distribution this BIEF, boosting polarization. Attributing synergy well‐matched impedance amplified loss, obtained hybrids exhibited superior (reflection −46.29 dB ultra‐wide effective bandwidth 7.6 GHz at only 1.6 mm). This work proves innovative model for dissecting mechanisms pioneers a novel advanced absorbers through enhancing BIEF.
