Abstract
Working with plasmonic materials involves many scientific steps, including, aside from the laboratory-level experiments, the numerical creation, their comparison, and the device fabrication. Besides these challenging steps, the design of new plasmonic materials with unique physical and chemical characteristics, and outstanding optical properties, which are traditional realms of gold and silver, merits an important place. Optimizing the material properties to improve their functionality and performance in plasmonic applications is a subsequent challenge to be tackled, also through iterative feedback from the experiments.This presentation will demonstrate an overview of recent advances in the computational design of potential future plasmonic materials, such as translational metals, transparent conducting oxides, or plasmonically active semiconductor allotropes, and their application in plasmonic structures, concepts, and devices. The extraction of complex dispersion characteristics from density functional theory (DFT) calculations allows the integration into subsequent electromagnetic modeling steps. This talk will illustrate the panorama of applying the so-developed materials into plasmonic particle investigations, ranging from isolated particles of various shapes and materials to self-assembled regular structures, exhibiting collective plasmonic crystal responses. The applications range from plasmonic sensing, metamaterials, and self-assembled particle clusters for surface-enhanced Raman scattering and catalysis.The Computational Materials Group at SDU investigates computational pathways, from the first-principles calculation-based molecular design to the three-dimensional multi-physical modeling of plasmonic nanostructures and plasmonically enabled devices for sensing, lighting, and catalysis applications. Our group recently developed the {
