Ultrafast Laser-Induced Photothermoelectric Currents in Graphene Junctions in the Mid-Infrared

Abstract We investigate the carrier dynamics in graphene junctions under mid-infrared excitation using ultrafast pump–probe photocurrent spectroscopy. We utilize dual split gate devices to demonstrate that the photothermoelectric effect can dominate the photocurrent response of g...
