13 May 2011 Silicon and nitride FETs for THz sensing
Author Affiliations +
Traditional THz electronics is using nonlinear properties of Schottky diodes for THz detectors and mixers and Gunn diodes driving frequency multiplier Schottky diode chains. Recently, ultra-short channel silicon CMOS and nitridebased transistors have demonstrated THz performance. New approaches use excitations of electron density in FET channels - called plasma waves - to generate and detect THz radiation, and extremely high sheet electron density in short channel AlN/GaN based HEMTs makes them especially suitable for applications in THz plasmonic devices.
