Abstract :
Antenna-coupled field effect transistors have been developed as plasma-wave THz detectors in both InAs nanowire and graphene channel materials. Room temperature operation has been achieved up to 3 THz, with noise equivalent power levels <; 10-10 W/Hz1/2, and high-speed response already suitable for large area THz imaging applications.
