17. Phthalocyanines on Surfaces : Monolayers, Films and Alkali Modified Structures
Abstract : The Phthalocyanines (Pc’s) are a group of macro-cyclic molecules, widely investigated due to the possibility to use them in a variety of applications. Electronic and geometrical structure investigations of molecular model systems of Pc’s adsorbed on surfaces are important for a deeper understanding of the functionality of different Pc-based devices.

18. Ab initio Interlayer Potentials For Metals and Alloys
Abstract : Many modern materials and material systems are layered. The properties related to layers are connected to interactions between atomic layers. In the present thesis, we introduce the interlayer potential (ILP), a novel model potential which fully describes the interaction between layers. READ MORE

19. Atom Dynamics and Diffusion on Surfaces
Abstract : This thesis is a theoretical study of atomic diffusion processes in condensed matter, with particular emphasis on surface diffusion. Oxygen adsorption and diffusion on the (111) surface of platinum is studied using a first-principles pseudopotential plane-wave approach based on density functional theory, with local (LDA) and semi-local functionals (GGA) for the exchange-correlation energy.
