21. Electronic structure studies of carbon based nanomaterials
Abstract : This thesis deals with theoretical investigations of the electronic structure of conjugated carbon based materials. Novel materials like the C60 fullerene and the carbon nanotubes, but also the more well known, but closely related, graphite phase of carbon were studied. READ MORE

22. Calculations of Linear and Nonlinear Optical Properties of Ionic Crystal Surfaces and Fullerenes
Abstract : Electronic and optical properties of ionic crystal surfaces and fullerenes have been studied by means of cluster calculations based on the Local Density Approximation (LDA) method using a numerical LCAO approach. The calculations for the bulk, stoichiometric and non-stoichiometric (111) surfaces of the divalent ionic crystals, CaF2 and BaF2, were based on the construction of an appropriate cluster of Ba++/Ca++ and F- ions representing a local environment of the specific system.

23. Charge Transport Simulations for Organic Electronics : A Kinetic Monte Carlo Approach
Abstract : In this thesis we focus on the modelling and simulation of organic electronic devices, investigating their structural and electronic properties. Organic devices have attracted great interest for their innovative properties, but their functioning still represent a theoretical and technological challenge. READ MORE

24. Electron transfer in slow collisions of highly charged ions with atoms and molecules
Abstract : Several spectroscopic methods have been used to study single- and double electron transfer in slow collisions between highly charged ions with neutral atoms and the C60 molecule.Radiative and non-radiative decay from high-lying doubly-excited states, populated in slow (v = 0.40 a.u.

25. Microstructure aspects of transition metal carbide thin films
Abstract : Transition metal carbides are important refractory materials used in many thin film applications. In this thesis, several transition metal carbides have been deposited using different chemical vapour deposition (CVD) and evaporation processes. In particular, the phase composition and microstructure of these carbide films have been studied. READ MORE
