  2. 1. Electronic Structure Calculations of Point Defects in Semiconductors

    Author : Andreas Höglund; Susanne Mirbt; Alison Mainwood; Uppsala universitet; []
    Keywords : Physics; electronic structure calculations; point defects; semiconductor; formation energy; equilibrium solubility limit; thermodynamic equilibrium concentration; transfer levels; negative-U; 110 surface; diffusion; activation energy; solar cells; Fysik;

    Abstract : In this thesis point defects in semiconductors are studied by electronic structure calculations. Results are presented for the stability and equilibrium concentrations of native defects in GaP, InP, InAs, and InSb, for the entire range of doping conditions and stoichiometry. READ MORE

    Abstract : Diamond has since many years been applied in electronic fields due to its extraordinary properties. Substitutional dopants and surface functionalization have also been introduced in order to improve the electrochemical properties. READ MORE

  5. 3. Fluorescence studies of complex systems : organisation of biomolecules

    Author : Denys Marushchak; Lennart B.A. Johansson; Alexander Lyubartsev; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fluorescence anisotropy; BODIPY; homo and hetero dimerisation; protein aggregates; protein polymer structures; actin polymerisation; FRET; donor–acceptor energy transfer DAET; donor-donor energy migration DDEM; homotransfer; Monte Carlo simulation; MC; Brownian dynamics; BD; Genetic Algorithm; GA.; Ganglioside GM1; Biophysical chemistry; Biofysikalisk kemi;

    Abstract : The homo and hetero dimerisation of two spectroscopically different chromophores were studied, namely: 4,4-difluoro-4-bora-3a,4a-diazas-indacene (g-BODIPY) and its 5-styryl-derivative (r-BODIPY). Various spectroscopic properties of the r-BODIPY in different common solvents were determined. READ MORE
