    Abstract : This PhD thesis summarizes the work carried on the optical characterizations of some Si-based self-assembled nanostructures, particularly SiGe/Si quantum dots (QDs) and nanocrystalline (nc)-Si embedded in mesoporous silica (MS) using photoconductivity (PC), photoluminescence (PL), and photoluminescence excitation (PLE) measurements. The spectroscopic studies of SiGe/Si QDs grown on Si by molecular beam epitaxy revealed for the first time well-resolved PLE resonances. READ MORE

  4. 17. Optically detected magnetic resonance studies of intrinsic defects in dilute nitrides and SiC

    Author : Nguyen Quoc Thinh; Marek Godlewski; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Self-interstitials, vacancies and antisites belong to an important class of defects -intrinsic defects - in compound semiconductors. They have been found to be common occurring defects in semiconductor crystals grown under non-optimized or non-equilibrium conditions or subject to high-energy particle bombardment. READ MORE
