  1. 1. Characterization of InAs-Al semiconductor-superconductor hybrid devices

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Markus Aspegren; [2020]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 2. An analysis of wastes in the construction industry - a case study of Ebbepark

    University essay from Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska högskolan

    Author : David Lagg; Niklas Waldt; [2020]
    Keywords : ;

    Abstract : Inefficient use of resources occurs in many industries, including both time and materials being wasted. A theory which has been used for a long time to reduce waste of resources in all supply chains is the SCM theory. READ MORE

  4. 3. Supercurrents in a Topological Josephson Junction with a Magnetic Quantum Dot

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Adam Szewczyk; [2018]
    Keywords : Majorana; Andreev; Keldysh; Josephson; density of states; quantum transport; topological superconductor; magnet;

    Abstract : The purpose of this master thesis is to investigate theoretically the influence of a nanomagnet on the Josephson effect displayed by phase biased point contacts consisting of topological superconductors. The device is modeled using the nonequilibrium Keldysh Green’s function technique. First, the Gor’kov Green’s functions are calculated. READ MORE
