Abstract :
We report on a novel type of wavelength-tunable terahertz (THz) detector based on a graphene transistor. We have demonstrated that the graphene under a magnetic field has the ability to detect THz waves in a wide range of 1.6-33THz. Further enhancement of the detection performance will be discussed.
