| Popis: | We report on detection of terahertz radiation by using bilayer graphene-based FET with asymmetric grating gates. The device was fabricated with a stack of h-BN/Graphene/h-BN with a back gate as well as an asymmetric dual grating top gates. It was subjected to terahertz radiation at frequencies of 150 and 300 GHz at 4K and a clear photocurrent was obtained. |
