## Description

- description: 'Finding new optoelectronic mechanisms that overcome the limitations
    of conventional semiconductor devices is paramount for detecting and harvesting
    low-energy photons. A highly promising approach is to drive a current from the
    thermal energy added to the free-electron bath as a result of light absorption.
    Successful implementation of this strategy requires a broadband absorber where
    carriers interact among themselves more strongly than with phonons, as well as
    energy-selective contacts to extract the excess electronic heat. Here we show
    that graphene-WSe2-graphene heterostructure devices offer this possibility through
    the photo-thermionic effect: the absorbed photon energy in graphene is efficiently
    transferred to the electron bath, leading to a thermalized ''hot'' carrier distribution. '
