   Sammanfattning : 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. LÄS MER

3. 2. Characterization of InAs-Al semiconductor-superconductor hybrid devices

   Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Författare :Markus Aspegren; [2020]
   Nyckelord :quantum dot; superconductivity; quantum transport; josephson junction; spectroscopy; yu-shiba-rusinov; hybrid devices; sub-gap states; quantum computer; majorana bound state; bogoliubov quasiparticle; Physics and Astronomy;

   Sammanfattning : In this thesis we study charge and spin transport through InAs-Al nanowire superconductor-semiconductor hybrid devices. We focus on assessing the quality of the InAs-Al contact interface when using a weak HCl acid to wet-etch the nanowire surface prior to metal evaporation. LÄS MER
