6. Source and drain engineering in SiGe-based pMOS transistors
Sammanfattning : A new shallow junction formation process, based on selective silicon etching followed by selective growth of in situ B-doped SiGe, is presented. The approach is advantageous compared to conventional ion implantation followed by thermal activation, because perfectly abrupt, low resistivity junctions of arbitrary depth can be obtained. LÄS MER
7. Characterization and Functionalization of 2D Overlayers Adsorbed on Transition Metals
Sammanfattning : Two-dimensional layered materials, namely monolayer hexagonal boron nitride and graphene were grown by CVD on various transition metals. The physical and chemical properties of these systems were characterized systematically using synchrotron-based spectroscopic techniques, scanning tunneling microscopy and low energy electron diffraction.

8. Electronic Structure and Atomistic Spin Dynamics of Nanostructured Materials
Sammanfattning : The theoretical studies of several magnetic materials are presented in this thesis. To each of them, it was investigated the electronic structure, by means of density functional theory calculations, and/or magnetization dynamics, in the context of atomistic spin dynamics (ASD).

9. From Facets to Flow: The Electrooxidation of Glycerol on Pd-based catalysts
Sammanfattning : Glycerol, a by-product of biodiesel refineries, has uses in industries such as cosmetics, food, and pharmaceuticals. However, its usage is small compared to the amount of glycerol produced from biodiesel production. LÄS MER
10. Ab initio Interlayer Potentials For Metals and Alloys
Sammanfattning : 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. LÄS MER
