  2. 21. Electronic properties of complex interfaces and nanostructures

    Author : Paulo V. C. Medeiros; Sven Stafström; Gueorgui Gueorguiev; Jonas Björk; Arkady Krasheninnikov; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis investigates the structural and electronic properties of graphene, polyaromatic hydrocarbon (PAH) molecules, and other carbon-based materials, when interacting with metallic surfaces, as well as under the influence of different types of perturbations. Density functional theory, incorporating van der Waals interactions, has been employed. READ MORE

  5. 23. Correlated Electronic Structure of Materials : Development and Application of Dynamical Mean Field Theory

    Author : Patrik Thunström; Olle Eriksson; Alexander Lichtenstein; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DFT; DMFT; correlation; entanglement; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : This thesis is dedicated to the development, implementation and application of a combination of Density Functional Theory and Dynamical Mean Field Theory. The resulting program is shown through several examples to be a powerful and flexible tool for calculating the electronic structure of strongly correlated materials. READ MORE

  6. 24. Electronic Structure of π-Conjugated Materials and Their Effect on Organic Photovoltaics
