description: This work is devoted to the study of the optical and electro-optical properties of a nanostructure with GaAs / Al0.4Ga0.6As quantum wells doped with beryllium at different temperatures. The research set the following goals: 1. Study of photoluminescence spectra in the near IR region at different temperatures. 2. Study of the spectra of photoconductivity in a wide range of wavelengths at cryogenic temperatures. 3. Study of the temperature dependence of electrical conductivity. 4. Determination of the ionization energy of acceptors in quantum well. The work was carried out at SPbPU in the Laboratory of Physics of Semiconductors and Nanoelectronics, where experiments were carried out to study luminescence at different temperatures using a Horiba Jobin Yvon FHR-640 grating monochromator. Experimental studies of photoconductivity at cryogenic temperatures were carried out using vacuum Fourier spectrometer Bruker Vertex. We analyzed the features of the photoluminescence and photoconductivity spectra, which are in a good agreement with the theoretical values of the energies of optical transitions of charge carriers in the structure. The ionization energy of the acceptor impurity in the structure were also determined by different methods; its value corresponds to the theoretical calculation of the energy spectrum of the structure.
