This emitter consists of asymmetric Schottky contacts on GaN layer, inducing an internal electric field. By radiating a short pulse with the wavelength of 350 nm, carriers are generated in the photoconductive active region. Rapid transition in the incident laser pulse, results in generation of high frequency components in the generated electric current. The resulted time varying current generates the THz radiation toward the bottom of the device. CP - IRAN IN - LG - eng PB - opsi PG - 145 PT - Research YR - 2018
