摘要：

缺陷调控是开发新型吸收材料的关键。如何精确控制缺陷的浓度和数量以优化材料的损耗机制仍然是一项重大挑战。传统吸收材料的吸收频率与谐振频率不匹配，限制了其吸收性能。为解决这些问题，本文通过磷掺杂和硫空位缺陷的协同作用，成功调控了CoMn纳米片的偶极子和载流子浓度，显著提高了材料的电磁波吸收性能。实验结果表明，优化后的复合材料在厚度分别为2.0 mm和2.2 mm时，实现了−52.19 dB的最小反射损耗(RLmin)和5.52 GHz的最大有效吸收带宽(EABmax)。磷掺杂和硫空位缺陷的引入不仅增加了活性位点，而且通过异质界面和晶格畸变丰富了损耗机制。本研究不仅提供了一种制备新型电磁波吸收材料的简便方法，而且为过渡金属二硫化物缺陷调控提供了一种新策略。

Abstract:

Defect regulation is a key to developing new types of absorbing materials. How to precisely control the concentration and quantity of defects to optimize the loss mechanism of materials remains a major challenge. The absorption frequency of traditional absorbing materials does not match the resonance frequency, which limits their absorption performance. To address these issues, this paper successfully regulated the dipole and carrier density of CoMn nanosheets through the synergistic effect of phosphorus doping and sulfur vacancy defects, significantly improving the electromagnetic wave absorption performance of the material. Experimental results show that the optimized composite material achieves a minimum reflection loss (RLmin) of −52.19 dB and a maximum effective absorption bandwidth (EABmax) of 5.52 GHz at matching thicknesses of 2.0 mm and 2.2 mm, respectively. The introduction of phosphorus doping and sulfur vacancy defects not only increases the active sites but also enriches the loss mechanism through the formation of heterointerfaces and lattice distortions. This study not only provides a simple method for the preparation of new electromagnetic wave absorbing materials but also offers a new strategy for defect regulation of transition metal dichalcogenides.
