  1. 1. Humidity dependent conductivity of air in HVDC applications and the role of surfaces

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets fysik

    Författare :Erik Svensson; [2023]
    Nyckelord :HVDC; humidity; air conductivity; thin films; HVDC; luftfuktighet; luftkonduktivitet; tunna filmer;

    Sammanfattning : High Voltage Direct Current (HVDC) bushings are insulated devices designed to facilitate the safe passage of electric current across an earthed barrier. Understanding air conductivity is of utmost importance in the design of HVDC components, which is determined by ion density and ion mobility. LÄS MER

  3. 2. Sputtered Transparent Contact Layers for Bifacial and Tandem Solar Cells

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Solcellsteknik

    Författare :Klara Kiselman; [2022]
    Nyckelord :Solar cells; ITO; indium doped tin oxide; bifacial cell; tandem cell; transparent conductive oxides;

    Sammanfattning : A key to solar cells with lower environmental impact is higher efficiency and reduced material usages. Bifacial solar cells may have a higher efficiency as light can enter from two directions and tandem solar cells may use a larger part of the incoming solar spectrum, increasing the efficiency.

  4. 3. Synthesis and thermoelectric properties of Cr1-xMexN (Me = Mo, V)

    Master-uppsats, Linköpings universitet/Tunnfilmsfysik

    Författare :Victor Rutberg; [2022]
    Nyckelord :Chromium nitride; thin films; thermoelectrics; physical vapour deposition; medium entropy alloy;

    Sammanfattning : Among emerging materials systems for thermoelectric applications, the early transition-metal nitrides based on ScN and CrN show unexpectedly promising properties. These properties are determined by high Seebeck coefficient, low thermal conductivity, and high electrical conductivity. LÄS MER

  5. 4. Computations of the Perpendicular Magnetic Anisotropy Energy of Permalloy

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Luca Mikadze; [2022]
    Nyckelord :permalloy; perpendicular magnetic anisotropy; perpendicular magnetic anisotropy energy; magnetocrystalline anisotropy; magnetocrystalline anisotropy energy; thin film; density functional theory;

    Sammanfattning : Magnetic materials have many applications in technology. The magnetic properties of materials are therefore important to catalogue for future use. In this project, the magnetic properties of thin films of permalloy are investigated. LÄS MER

  7. 5. AI Trained to Predict Thresholds of 2D Ellipse Percolation Systems

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Nirav Surajlal; [2021]
    Nyckelord :Low-dimensional Nanomaterials; Percolation Threshold; Machine Learning; Regression; Two-dimensional Heterogeneous Ellipse System; Lågdimensionella nanomaterial; Perkolering Tröskel; Maskininlärning; Regression; Tvådimensionellt Heterogent Ellipssystem;

    Sammanfattning : Percolation theory is a relevant area of research in Nanotechnology because of its wide applications in nanoelectronics based on thin films of nanoparticles and composites, amongst others. In nanotechnology, systems are often explored through modelling and simulations. LÄS MER
