N2 - Graphene is a promising candidate for the development of detectors of Terahertz (THz) radiation.A well-known detection scheme due to Dyakonov and Shur exploits plasma waves in a field-effecttransistor (FET), whereby a dc photovoltage is generated in response to a THz field. In the questfor devices with a better signal-to-noise ratio, we theoretically investigate a plasma-wavephotodetector in which a dc photocurrent is generated in a graphene FET. The noise equivalentpower of our device is shown to be much smaller than that of a Dyakonov-Shur detector in a widespectral range
