11. Quantum Devices from the Assembly of Zero- and One-Dimensional Building Blocks
Sammanfattning : This thesis describes novel methods for the fabrication of nanometer-scale electronic devices, such as single-electron transistors and resonant tunneling diodes, from wire- and dot-shaped building blocks. The first part of the thesis describes the manipulation of metal nanoparticles and carbon nanotubes using an atomic force microscope. LÄS MER
12. Linking Probability Theory and Quantum Mechanics, and a Novel Formulation of Quantization
Sammanfattning : This doctoral thesis in mathematics consists of three articles that explore the probabilistic structure of quantum mechanics and quantization from a novel perspective.The thesis adopts a probabilistic interpretation of quantum mechanics, which views the archetypical quantum experiments of Bell- and double-slit- type as violating the principle of non-contextuality, i.

13. Epitaxial Growth, Processing and Characterization of Semiconductor Nanostructures
Sammanfattning : This thesis deals with the growth, processing and characterization of nano-sized structures, eg., self-assembled quantum dots and nano-wires. LÄS MER
14. Spectral Inequalities and Their Applications in Quantum Mechanics
Sammanfattning : The work presented in this thesis revolves around spectral inequalities and their applications in quantum mechanics.In Paper A, the ground state energy of an atom confined to two dimensions is analyzed in the limit when the charge of the nucleus Z becomes very large. LÄS MER
15. Measuring quantum systems with a tunnel junction
Sammanfattning : This thesis is concerned with employing the statistics of charge transfer in a conductor as a tool for quantum measurement. The physical systems studied are electronic devices made by nanoscale manufacturing techniques. In this context quantum measurement appears not as a postulate, but as physical process. LÄS MER
