hBN-Encapsulated Graphene Coupled to a Plasmonic Metasurface via 1D Electrodes for Photodetection Applications

Abstract

In article number 2300192, Christian Frydendahl, Uriel Levy, and co-workers demonstrate a new approach where plasmonic nanostructures are pierced through the hexagonal boron nitride layers to make atomic edge contacts to the graphene, thus maintaining the advantages of encapsulation, while enabling strong enhancement of the optical response of graphene from charge transfer from plasmonic decay in the nanocavities.
