Graphene-based metamaterials for solar energy harvesting

This project aims to develop plasmonic nanostructures and graphene-based metamaterials for use in solar thermal energy harvesting. In this project, combining numerical simulations, nanofabrication and characterization techniques, we will study the light-matter interactions at nanoscale. We try to figure out the physical mechanism of photon-phonon-electron interactions at nanoscale, providing the details of photothermal manipulation by ultrathin graphene grating metamaterials or plasmonic nanostructures. Also, we will study the photothermal performance of these developed nanostructures and directly integrate them into practical applications, such as solar thermal harvesting, thermal cloak, and sensing.
