We demonstrate two different Terahertz (THz) rectification mechanisms by graphene field effect transistors: 1) a standard rectification mechanism where THz radiation modulates simultaneously the carrier density and the carrier velocity, and 2) a mesoscopic rectification due to the existence of the nonlinearity associated to the quantum interference effects.

Abstract
We demonstrate two different Terahertz (THz) rectification mechanisms by graphene field effect transistors: 1) a standard rectification mechanism where THz radiation modulates simultaneously the carrier density and the carrier velocity, and 2) a mesoscopic rectification due to the existence of the nonlinearity associated to the quantum interference effects.File in questo prodotto:
