We are devoted to detection and emission of terahertz radiation at room temperature by using submicron size transistors and characterization of solar cell (IV, CV, Quantum efficiency, …). We dispose of different equipment listed below as well as a license of TCAD Synopsys and Monte Carlo software, Pyroelectric detectors, quantum cascade lasers at 2.5THz and other different instruments (Lock-in amplifiers, pulse generators, sourcemeters,…).
