  1. 1. A theoretical framework for interpretation and prediction of magneto-optical measurements

    University essay from Uppsala universitet/Materialteori

    Author : Viktor Frilén; [2023]
    Keywords : moke; tmoke; lmoke; pmoke; magneto-optical effects; layered media; dielectric function; maxwells equations; dielectric tensor; linear respons; magnetism; light induced transistions; DFT; SO;

    Abstract : The interplay of experiments and theory is essential to deepen our understanding of magnetization dynamics. This thesis aims to serve as a bridge between these two aspects by establishing a mathematical framework that enables the computation of optical observable quantities based on theoretical models.

  4. 3. Investigation of charge injection at electrode-dielectric interface relevant for HVDC cables : Simulation of charge injection and transport dynamics in electrical insulation for HVDC cables

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Mohammed Mosa; [2023]
    Keywords : BCT model; charge injection; space charge density; electric field distribution; Fowler-Nordheim; Richardson-Schottky;

    Abstract : A bipolar charge transport (BCT) model is used to simulate charge injection and transportdynamics inside insulation material which are used in a high voltage direct current (HVDC)cable. Gaining knowledge about space charge density and electric field distribution in theinsulation material enables minimising charge injection at the metal-insulator interface andavoiding unnecessary energy loss.

    Abstract : Electrical insulation papers are a widely used group of papers in insulation applications and has been used for more than 100 years. Common applications include use as the dielectric medium in capacitors and insulation material in cables, bushings and transformers. READ MORE

  6. 5. Fabrication of sub-10 nm solid-state nanopores by electrical breakdown

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Kasumi Tsutsumi; [2023]
    Keywords : Nanopore fabrication; Solid-state material; Silicon nitride; Graphene; DNA translocation; Nanopor-avkänning; fast tillståndsmaterial; kiselnitrid; grafen; DNA-translokation;

    Abstract : Nanopore sensing is a versatile technique that employs very small openings, known as nanopores, to study biomolecules. The use of nanopores on solid-state membranes has gained attention due to its potential for low-cost and high-throughput sensing of single molecules in liquids. READ MORE
