Materials discovery for optical metasurfaces

Optical metasurfaces are flat optical devices capable of tailoring the flow of light in a desired fashion. The most promising materials for constructing metasurfaces are semiconductors due to their high refractive index and low absorption losses. This project explores a new approach for identifying, fabricating, and experimentally demonstrating the potential of a wide range of new semiconductor nanomaterials. The aim is to map the landscape of available semiconductor materials from which metasurfaces can be constructed. This would constitute the first experimentally tested optical materials library and set the foundation for next-generation metasurface devices.
