Conference: 2012 37TH INTERNATIONAL CONFERENCE ON INFRARED, MILLIMETER, AND TERAHERTZ WAVES (IRMMW-THZ) (Wollongong, NSW, AU, 2012-09-23) Ref HAL: hal-00816693_v1 DOI: 10.1109/IRMMW-THz.2012.6380119 Exporter : BibTex | endNote Résumé: We demonstrate two different THz rectification mechanisms by graphene field effect transistors: a mesoscopic rectification due to the existence of 2nd-order conductance fluctuations and a rectification mechanism where THz radiation modulates simultaneously carrier velocity and carrier density. |
