## Description

- description: It is shown here how encapsulated graphene devices can be laterally
    coupled to plasmonic metasurfaces via 1D edge contacts, preserving the high mobility
    of encapsulated graphene while enhancing optical coupling. The device is used
    for photodetection applications where high responsivities in the range of 100 A W−1
    for most of the visible spectrum are reported. The device exhibits a photogating
    effect which is attributed to defect states in the encapsulating hBN layers. The
    results highlight a new configuration to couple graphene with plasmonic structures
    and points to a new type of device based on defect states and graphene's excellent
    transport properties to achieve photodetectors with ultrahigh responsivities.
