1. Laser sintered materials with Non-equilibrium structures
Sammanfattning : This thesis is focused on achieving materials with non-equilibrium structures fabricated by high-energy laser sintering. The chosen precursor materials have rigid and inert structures like high-melting point ceramics or metals. LÄS MER
2. Non-equilibrium Surfaces of Metallic Thin Films
Sammanfattning : Growth and structural characterization of metallic multilayers have been performed on the Mo/W, Mo/V and Ag/Ni systems utilizing magnetron sputtering under ultra-high-vacuum deposition conditions. Structural characterization has been performed both in situ and ex situ with several electron beam probing techniques as well as x-ray diffraction. LÄS MER
3. Transport theory and finite element methods for mesoscopic superconducting devices
Sammanfattning : At low temperatures, electrons in a superconductor exhibit pairing correlations that result in a macroscopic, phase-coherent ground state. This leads to peculiar electromagnetic properties such as the flow of dissipationless charge currents and expelling of external magnetic fields. LÄS MER
4. Polymers in Aqueous Lubrication
Sammanfattning : The main objective of this thesis work was to gain understanding of the layer properties and polymer structures that were able to aid lubrication in aqueous media. To this end, three types of polyelectrolytes: a diblock copolymer, a train-of-brushes and two brush-with-anchor mucins have been utilized. LÄS MER
5. Electrical Characterization of Novel Insulators in Metal-Insulator-Semiconductor Structures
Sammanfattning : This thesis comprises seven papers (A-G) and an extended introduction which puts them into context within a broader field of research. The papers deal with the electrical characterization of some different insulators and interfaces encountered within the realm of silicon based microelectronics. LÄS MER
