Abstract

New doubly interdigitated grating gate high-electron mobility transistor (HEMT) was illuminated at room temperature by a 1.5-μm CW laser. A clear emission of the terahertz radiation has been detected using a Silicon bolometer cooled down to 4.2 K and placed in the front of the sample. The observed signal was related to the self oscillation of the plasma waves in our new HEMT device.
