1. Quantum Transport in Topological Insulator Nanowires
University essay from KTH/FysikAbstract : Three-dimensional topological insulators are materials that have a bulk band gap like a traditional insulator, but which hold topologically protected conducting surface states. In this thesis we present a numerical analysis of the surface states of topological insulator nanowires in the tight-binding approximation. READ MORE

2. Benchtop conductance quantization
University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)Abstract : Quantum conductance is a phenomenon associated with nanowires / quantum point contacts where the current through a wire is quantized. Experiments have shown that this phenomenon can be manifested at room temperature using macroscopic wires. This project is aimed to recreate these experiments with emphasis on simplicity. READ MORE

3. Computational simulations of the Axion Longitudinal Plasma HAloscope
University essay from Stockholms universitet/FysikumAbstract : The quantum chromodynamics axion is a very light hypothetical particle that may simultaneously solve the dark matter and the strong CP problem. Recently, a new type of haloscope that can detect the resonant conversion of axions to photons was suggested, The Axion Longitudinal Plasma HAloscope (ALPHA). READ MORE

4. Simulating the Effect of Spatial Potential Variation in Nanodevices with the NEGF Method
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : In this master thesis nanowires have been simulated to study the effect of spatial imperfections in the nanowires. This spatial imper- fection took the form of potential fluctuations in the conduction band across the wire. READ MORE

5. Investigations of p-type quantum dots in GaSb nanowires
University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenAbstract : The purpose of this project is to investigate hole transport in p-type quantum dots formed in GaSb nanowire and operating as single hole transistors. The individual and controlled hole-spin confinement in such system yields a variety of proposed applications for spintronics or quantum computation. READ MORE
