Object: CdSe/ZnSe, InAs/GaSb, InAs/AlSb, GaAs/AlAs quantum wells and superlattices obtained by molecular beam epitaxy. Aim: Technological, structural and optics investigations A2B6 and A3B5 geterostructures and superlattices with ultrafine layers for the nanoelectronic devices. Methods: Resonance Raman scattering, photoluminescence, polarization methods, non-linear optic and laser spectroscopy. Stage 1. Self-organize mechanism and relations between structure and optical (photoluminescence and Raman scattering) properties investigation of CdSe/ZnSe quantum structure with 0.5-3.15 ML thickness. Stage 2. Investigation of the influence BeSe layer on the defect formation, density, composition and size of CdSe/ZnSe quantum islands. Correlation between structure and emitting properties of (In, Ga, Al)As quantum structures. Magnetoluminescence and ellipsometric investigations of quantum structures. Development optical micro diagnostic for the A3B5- and A2B6-based laser nanostructures. The quantum-size effect in phonon spectra of A2B6 and A3B5 semiconductor structures was investigated by Raman scattering. The composition, strain, deformations and exciton energy were evaluated. The physical mechanism of anti-Stocks photoluminescence and Stocks Raman scattering of CdSe/ZnSe geterostructures was studied. Have been investigated defects dynamic, structural quality, concentration and electron mobility in InAs/GaSb and InAs/AlSb quantum well from the behavior of the phonon mode and plasmon-phonon mode. Keywords: Molecular Beam Epitaxy, Geterostructures, Quantum well, Quantum Dots, Spectroscopy, Photoluminescence, Raman scattering. Product Description popup.authors popup.nrat_date 2020-04-02 Close
