Abstract

Emission of terahertz (THz) radiations from interdigitated GaN quantum-wells structures under DC-bias has been measured at room temperature. This measurements has been performed by a 4K Si-Bolometer associated with a Fourier Transform Spectrometer. Using an analytical model, we have shown that the observed peak at approximately 3 THz due to 2D ungated plasma-waves oscillations in the quantum well, is emitted by the metallic contacts of our device acting as antennas.
