Abstract :
The oscillation frequencies of the electron density (called plasma waves) in short channel devices correspond to the terahertz (THz) frequency range, and excitation of plasma waves can be used for generating and detecting THz radiation. Plasma wave THz detectors already outperform more conventional THz detectors, but achieving the full potential of plasma wave electronics devices may require use of grating-gate devices and/or plasmonic crystals, which are 2D or 3D arrays of plasmonic FETs.
