The Waterloo Institute for Nanotechnology (WIN) presents a seminar by Professor Wojciech Knap, Research Director at the Charles Coulomb Laboratory, Montpellier University and CNRS, France, and Institute of High Pressure Physics at the Polish Academy of Sciences Warsaw, Poland.
Terahertz Imaging with Nanometer Field Effect Transistors - from Basic Physics to First Fast Terahertz Scanners
An overview of main results concerning THz detection related to plasma nonlinearities in nanometer field effect transistors is presented. In particular nonlinearity and dynamic range of these detectors are discussed. We present also results on THz detection by Graphene field effect transistors. As a conclusion, we will show one of the first real world application of the FET THz detectors: a demonstrator of the imager developed for fast postal security imaging.
