  1. 1. Majorana bound states in Rashba nanowire junctions

    L3-uppsats, Uppsala universitet/Materialteori

    Författare :Lucas Baldo Mesa Casa; [2020]
    Nyckelord :Topological superconductivity; Rashba nanowires; Majorana Bound States;

    Sammanfattning : Nanowires with Rashba spin-orbit coupling represent a promising platform for the realization of one-dimensional topological superconductivity and Majorana bound states. In this work we investigate Majorana bound states in hybrid normal-superconductor and short superconductor-normal-superconductor junctions based on nanowires with Rashba spin-orbit coupling. LÄS MER

  3. 2. The Effect of Fano Resonance on ExchangeInteraction in a DQD Junction with RashbaSpin-Orbit Coupling

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :Seif Alwan; [2019]
    Nyckelord :;

    Sammanfattning : In this work, we investigate electronic transport through a double quantum dot junction, where each dot couple to external localized spins. The junction is embedded in between two metallic leads,functioning as continues electron reservoirs. LÄS MER

  4. 3. Theoretical understanding and calculation of the Edelstein effect

    Kandidat-uppsats,

    Författare :Gustav Eriksson; Hampus Nyström; [2017]
    Nyckelord :edelstein effect; spin polarization;

    Sammanfattning : The main topic of this project is the so called Edelstein effect. This recently discovered effect consists in the possibility of converting an electric field (a current) into a magnetization in materials that fulfill specific characteristics, more specifically materials where an effective Rashba spin-orbit coupling is present.

  5. 4. Spin-FET based on InGaAs/InP heterostructure

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

    Författare :Ricardo Moreira Salles De Andrade; [2011]
    Nyckelord :Spin; Spintronics; Field-effect transistor; Datta-Das transistor; Rashba effect; Low-temperature.; Physics and Astronomy;

    Sammanfattning : A new design based on the spinFET proposed by Datta-Das was fabricated, using a channel defined by etching on a 2DEG material and nanomagnets as top-gates. The magnetotransports properties were measured at low temperatures. LÄS MER
