Abstract
In this paper, millimeter-wave detection is conducted for the first time on the basis of graphene photo-thermoelectric effect. Upon receiving millimeter-wave radiation, graphene generates hot carriers which diffuse towards the nearby drain and source contact metals, and causing a differential drain-source voltage. To optimize detection performance, devices with different drain and source contact metals as well as graphene geometries are designed and tested. Measured results show that using Yb-graphene-Au metal combination with a 25 μm contact length perform the best, with a responsivity of 1.99 V/W.
