Abstract:In recent years, plasmonics and metamaterials have seen an explosion of novel ideas and device designs.
However, transforming these concepts into practical devices requires a significant amount of effort. The
constituent materials in these devices play a crucial role in realizing useful and efficient devices. Similar to
the way silicon shaped the nanoelectronics field, efforts toward finding the best set of materials for
plasmonic and metamaterial devices could revolutionize the field of nanophotonics. As a potential solution,
alternative plasmonic materials have recently gained significant attention. Metals, despite being essential
components of plasmonic and metamaterial devices, pose many technological challenges toward the
realization of practical devices—primarily due to their high optical loss, integration and fabrication
limitations. Hence, searching for an alternative to metals is vital to the success of future nanophotonic
devices. In this talk, I will provide a brief survey of recent developments in the pursuit of better plasmonic
materials, and discuss several classes of materials including doped semiconductor oxides and ceramics as
potential alternatives to metals that provide low intrinsic loss, tunability and compatibility with standard
semiconductor fabrication processes.
