1. Interactions and coherences in electron transport through serially coupled quantum dots
Abstract : This thesis is considering various aspects of electronic transport through quantum dots, with the focus on two or three dots coupled in series.In paper I, we study the impact of electron-electron interactions on transport in a system of triple quantum dots with spin. READ MORE

2. Studies on hybrid superconducting junctions
Abstract : In the field of nanoelectronics, one seeks to combine quantum mechanical effects with macroscopic entities such as currents in order to find new ways of storing and manipulating information. One possibility to accomplish this is to use the quantum correlations found in superconductors. READ MORE

3. Resonant Tunneling in Laterally Confined Quantum Structures
Abstract : In the thesis, three-dimensionally confined resonant tunneling structures were studied experimentally. Two approaches were used for obtaining quantum confinement: gate-defined lateral constriction of double barrier structures, and epitaxial growth of self-assembled quantum dots. READ MORE

4. Transport Studies of Local-Gate Defined Quantum Dots in Nanowires
Abstract : This thesis focuses on electrical transport in semiconductor InAs nanowires grown by chemical beam epitaxy. Initially, transport length scales of homogeneous InAs n-type nanowires are characterized by low-temperature magnetoconductance measurements. The measurements show phase-coherent conductivity corrections. READ MORE

5. Theoretical Studies of Spin-Dependent Quantum Phenomena in Semiconductor Nanostructures
Abstract : The study of spin transport has emerged at the forefront of condensed matter physics during the last decade. Much of the interest has undoubtedly been sparked by the advent of the spintronics paradigm and the idea of creating novel electronic devices based on the spin degree of freedom of the carriers.
