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

    University essay from Uppsala universitet/Materialteori

    Author : Seif Alwan; [2019]
    Keywords : ;

    Abstract : 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. READ MORE

  2. 2. Theoretical understanding and calculation of the Edelstein effect

    University essay from

    Author : Gustav Eriksson; Hampus Nyström; [2017]
    Keywords : edelstein effect; spin polarization;

    Abstract : 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.

  3. 3. Majorana Fermions in Topological Quantum Matter

    University essay from Chalmers tekniska högskola/Institutionen för fundamental fysik

    Author : Pontus Laurell; [2012]
    Keywords : Topological insulators; Quantum spin Hall effect; Spin-orbit interactions; Majorana fermions;

    Abstract : Two-dimensional topological insulators coupled to s-wave superconductors and external magnetic fields have been predicted to support Majorana edge states. The stability of these states against electron-electron interactions and spin-orbit interactions of Rashba and Dresselhaus type are studied using bosonization and renormalization group analysis.

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

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

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

    Abstract : 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. READ MORE
