  • Abstract
    The THz emission from large-area-grating coupler placed on the 2DEG AlGaN/GaN heterostructures was measured at frequency range 0.3-30 THz and temperature from 300 to 500 K with high spectral accuracy. The THz emission spectrum below 10 THz was found to be close to the thermal black-body radiation. Indistinct radiation modified with 2DEG plasma resonances was observed at frequencies below 3 THz.
