## Description

- description: "One of the most captivating properties of polaritons is their capacity
    to confine light at the nanoscale. This confinement is even more extreme in two-dimensional
    (2D) materials. 2D polaritons have been investigated by optical measurements using
    an external photodetector. However, their effective spectrally resolved elec-
    trical detection via far-field excitation remains unexplored. This fact hinders
    their potential exploitation in crucial applications such as sensing molecules
    and gases, hyperspectral imaging and optical spectrometry, banking on their potential
    for integration with silicon technologies. Herein, we present the first electrical
    spectroscopy of polaritonic nanoresonators based on a high-quality 2D-material
    heterostructure, which serves at the same time as the photodetector and the polari-
    tonic platform. We employ metallic nanorods to create hybrid nanoresonators within
    the hybrid plasmon-phonon polaritonic medium in the mid and long-wave infrared
    ranges. Subsequently, we electrically detect these resonators by near- field coupling
    to a graphene pn-junction. The nanoresonators simultaneously present a record
    of lateral confinement and high-quality factors up to ∼200, exhibiting prominent
    peaks in the photocurrent spectrum. We exploit the geomet- rical and gate tunability
    of these nanoresonators to investigate their impact on the photocurrent spectrum.
    This work opens a venue for studying this highly tunable and complex hybrid system,
    as well as for using it in compact platforms for sensing and photodetection applications.\r\n"
