description: The subject of the graduate qualification work is: âDouble resonance Raman scattering with LO phonon creation in (Cd, Mn)Te quantum wellâ.Â This work is concerned with investigating double resonance Raman scattering with LO phonon creation in dilute magnetic semiconductor quantum well CdMnTe/CdMgMnTe, which was grown using a molecular beam epitaxy method. A series of secondary emission spectra from the quantum well were measured under Raman scattering double resonance conditions in magnetic fields ranging from 0 to 3 T in Faraday and Voigt geometries and under the temperature of 1.5 K. In Faraday geometry, an eightfold increase in Ï+ LO peak intensity appeared when the sample was excited with Ïâ light in a magnetic field of 0.4 T. In Voigt geometry, the intensity of LO phonon signal decreased with magnetic field, and there was no apparent resonance. The set of magnetic fields satisfying the resonant conditions were established in Faraday and Voigt geometries by employing energy conservation principles. Nevertheless, Raman scattering with LO phonon creation only occurred in Faraday geometry when the energy difference between hole levels of electronic excitations, participating in double resonance, was equal to the LO phonon energy.
