Abstract

The new TeraFET design with identical source and drain antennas enables a tunable resonant polarization-sensitive plasmonic spectrometer operating in the sub-terahertz and terahertz (THz) range of frequencies at room temperature. It could be implemented in different materials systems including silicon. The p-diamond TeraFETs support operation in the 200 to 600 GHz windows.
