We present an experimental and theoretical study of the radiation power in the terahertz frequency range emitted by a GaAs/AlAs superlattice at 4-300 K. The non-biased superlattice was driven by an electric field with a frequency of 20 GHz. We measured the power spectrum of output signal and found that a decrease in the physical temperature leads to a significant increase in harmonic content.
