项目摘要
This project is devoted to the investigation of ordered plasmonic nanostructures by angle-resolved extinction spectroscopy and imaging spectro-ellipsometry with high spatial resolution. Structures for these investigations are prepared by electron beam lithography. Cylindrical nanoparticles are arranged in ordered lattices on a spacer separating those particles from an additional metallic layer (so-called metal-insulator-metal (MIM) structures). Such a system has a variety of electromagnetic resonances, spectral and geometrical position of which may be tuned besides the used materials by the geometrical parameters of the constituting nanoparticles, the lattice parameters, and the thickness of the spacer. In contrast to random distributions of nanoparticles, the lattice form-factor should provide an additional channel to manage the response of such systems with the same filling fraction of nanoparticles but different kinds of lattices. The use of extinction and imaging ellipsometry at different angles of incidence will allow both longitudinal and transverse resonances of the system to be excited and separated, revealing individual, lattice, and cooperative resonances as well as providing not only amplitude but phase information. The latter will help to reveal different interactions in such systems. Raman spectra will be taken to reveal the local plasmonic near-field enhancement of the investigated structures, while subsequent etching of the spacer will help to evaluate the role of the gap modes. The additional options of the ellipsometer system to be used enable the combination with atomic force microscopy (AFM) to determine the real arrangement of nanoparticles in the lattice and its orientation. Such additional information can be very valuable in the analysis of plasmonic properties of these structures.
本项目主要利用角分辨消光光谱和高空间分辨成像光谱-椭圆偏振技术研究有序等离子体纳米结构。这些研究的结构是用电子束光刻技术制备的。圆柱形纳米粒子排列在一个间隔层上,将这些粒子与额外的金属层(所谓的金属-绝缘体-金属(MIM)结构)分开。这种系统具有多种电磁共振、光谱和几何位置,除了使用的材料外,还可以通过构成纳米颗粒的几何参数、晶格参数和间隔层的厚度来调谐。与纳米颗粒的随机分布相反,晶格形式因子应该提供一个额外的通道来管理具有相同填充分数的纳米颗粒但不同类型晶格的系统的响应。在不同入射角下使用消光和成像椭偏仪将允许系统的纵向和横向共振被激发和分离,揭示单个、晶格和合作共振,并提供不仅振幅和相位信息。后者将有助于揭示这些系统中不同的相互作用。拉曼光谱将揭示所研究结构的局部等离子体近场增强,而随后的间隔层蚀刻将有助于评估间隙模式的作用。利用椭偏仪系统的附加选项,可以结合原子力显微镜(AFM)来确定纳米颗粒在晶格中的真实排列及其方向。这些附加信息在分析这些结构的等离子体特性时非常有价值。
