1. 21. Ion Induced Particle Desorption From Self Supporting Nanomembranes : Influence of Different Geometries and Particle Types

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Jonas Beling; [2023]
   Keywords : ion; physics; ion physic; scattering; desorption; sputtering; jon; fysik; jonfysik;

   Abstract : Nanoelectronics is a field undergoing rapid development, meaning knowledge of the materials and methods used in nano-scale systems is a driving force in the industry. Silicon is a well known material in nanoelectronics commonly used as a semiconductor and is therefore a good representative for nanomaterials in general. READ MORE

3. 22. THE COUPLING OF A DOUBLE QUANTUM DOT TO MICROWAVE PHOTONS

   University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Author : Mohamed Abrash; [2023]
   Keywords : Quantum computing; Qubit; Double quantum dot DQD ; Microwave resonator; Quantum integrated circuits; Sweet spots; Hybrid quantum circuits.; Physics and Astronomy;

   Abstract : In this study, we derive a mathematical description of a double quantum dot (DQD) embedded in a microwave resonator starting from classical electrostatics. DQDs are a promising platform for building quantum computers and have important applications in quantum sensing and the study of light-matter interactions. READ MORE

4. 23. 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.

5. 24. Experimental studies of radiation damage in uranium nitride

   University essay from KTH/Fysik

   Author : Maria Giamouridou; [2023]
   Keywords : uranium nitride nuclear fuel; advanced nuclear fuel; uranium nitride fabrication; uranium nitride characterisation; Spark Plasma Sintering; proton irradiation; irradiation damage; TANDEM accelerator; irradiation induced cracking; irradiation induced hardening; irradiation induced swelling; hydrogen implantation; dislocation loops; kärnbränsle av urannitrid; avancerat kärnbränsle; tillverkning av urannitrid; karakterisering av urannitrid; Spark Plasma Sintering; protonbestrålning; strålningsskador; TANDEM-accelerator; strålningsinducerad sprickbildning; strålningsinducerad härdning; strålningsinducerad svällning; väteimplantation; dislokationsloopar;

   Abstract : The effect of proton (H+) irradiation on uranium mononitride (UN) and UN compositefuel with 10 at.% ZrN (UN10at%ZrN) was examined. Protons of 2 MeV with fluences of1E17, 1E18, 1E19 and 1E20 ions/cm2 were accelerated towards the fabricated samples in orderto investigate the evolution of the micro-structure. READ MORE

6. 25. Hybrid Simulations of Solar Wind Plasma Interaction with the Lunar Reiner Gamma Magnetic Anomaly

   University essay from Umeå universitet/Institutionen för fysik

   Author : David Frisk Strömberg; [2023]
   Keywords : ;

   Abstract : The Moon has small scale regions of strong magnetic fields scattered over its surface, known as crustal fields. Coexisting with some of the strongest crustal fields are peculiar markings in the lunar soil, called lunar swirls, which are suggested to be formed by magnetosphere-like interactions between the crustal fields and the solar wind plasma.
