摘　　要：在后摩尔时代,二维材料因其在高性能光电集成器件中的潜力而成为研究的焦点。尽管这些材料展现出优异的物理性能,但其在极端环境下的稳定性和可靠性,尤其是电离辐射对其性能的影响,仍是一个未被充分解决的问题。深入探讨了电离辐射对二维材料微观结构和物性的影响,揭示了辐射引起的缺陷和掺杂如何改变材料的电学、光学和机械特性。强调了辐射类型和能量在决定二维材料器件性能中的重要性,指出适当的辐射参数可以提升材料性能,而过量辐射则可能导致性能下降。通过精确控制辐射参数,可以实现对二维材料性能的有效调控。还详细讨论了辐射处理后的二维材料在光刻和光传感等技术领域的应用,并对未来在空间探索、能源和国防等领域的应用前景和挑战进行了展望。In the post-Moore era,as traditional semiconductor technology approaches its physical limits,Two-dimensional(2D)materials have become a hot topic of research due to their unique physical properties.These materials,such as graphene,transition metal dichalcogenides,and black phosphorus,have garnered widespread attention in fields like materials science,condensed matter physics,and chemistry due to their strong exciton dipole moment,narrow linewidth,low disorder,and high binding energy.These characteristics give 2D materials potential applications in electronic devices,optoelectronics,and energy storage.Despite their excellent performance,their stability and reliability in practical applications,especially under extreme conditions,and particularly the impact of ionizing radiation on their performance,remain an issue that has not been fully resolved.Ionizing radiation,such as X-rays,gamma rays,and particle beams,can cause damage to materials,affecting their electronic structure and physical properties.Recent research has found that during the interaction between ionizing radiation and 2D materials,2D materials undergo a series of significant changes.These changes include the formation of defects,doping at the atomic level,adjustment of interlayer spacing,and morphological transformations.These changes not only provide new possibilities for controlling the performance of 2D materials but also reveal how radiation-induced defects and doping can alter the material's electrical,optical,and mechanical properties.The occurrence of these phenomena is mainly due to the complex interactions between incident ions and the target materials.This interaction is influenced by various factors,including the type of irradiation,ion species,irradiation parameters,types of 2D materials,and substrates.This article delves into and summarizes the impact of these factors on the microstructure and performance of 2D materials.The results show that the type and energy of radiation play a crucial role in determining the performance of 2D materi
