description: This work is devoted to the study of terahertz radiation in semiconductor nanoheterostructures. The object of study is samples with a set of pairs of tunnel-coupled quantum wells GaAs/AlGaAs. The research set the following goals:Development of an efficient design of a structure with tunnel-coupled quantum wells for generation in the THz range in the framework of solving the problem of maximizing the matrix element of an optical transition. Characterization of the grown structures by measuring photoluminescence spectra in the near-IR range. Studies both at different levels of optical pumping and at different temperatures. Registration of the integrated THz photoluminescence signal. The work was carried out at St. Petersburg Polytechnic University in the laboratory "Optics of nonequilibrium electrons", where experiments were carried out to study luminescence at different temperatures using a Horiba Jobin Yvon FHR-640 grating monochromator. Experimental studies of the THz photoluminescence spectra at cryogenic temperatures were carried out using. vacuum Fourier spectrometer Bruker Vertex. The features of the photoluminescence spectra were analyzed, which are in good agreement with theoretical calculations of the energies of optical transitions of charge carriers in the structure.
