  1. 1. Structural analysis of HZO thin film and electrode using X-ray diffraction

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Elliot Winsnes; [2024]
    Nyckelord :HZO; hafnia; hafnium dioxide; zirconium dioxide; ferroelectricity; ferroelectric; synchrotron radiation; X-ray diffraction; Physics and Astronomy;

    Sammanfattning : Since its discovery in 2011, the ferroelectricity of thin films based on HfO2 has been studied intensively. In particular, thin films with a 1:1 ratio of HfO2 and ZrO2 (HZO) has been of great interest. The ferroelectricity arises from a non-centrosymmetric orthorhombic (o) phase of HZO whose prevalence is dependent on the processing conditions. LÄS MER

  3. 2. Digitally Controlled Oscillator Topologies for mm-Wave Pulsed Coherent Radar

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Klas Junskog; [2023]
    Nyckelord :oscillators; mm-wave; radar; Technology and Engineering;

    Sammanfattning : The advancement of future generations of wireless communication and radar sensing warrants the need for mm-wave digitally controlled oscillators (DCOs) with high-frequency trade-offs in consideration. The purpose of this project is to investigate DCO topologies inspired from scientific literature. LÄS MER

  4. 3. Forecasting the Regulating Price in the Finnish Energy Market using the Multi-Horizon Quantile Recurrent Neural Network

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Thomas Hamfelt; [2020]
    Nyckelord :Energy; Finland; Regulating market; Balancing market; Deep learning; Quantile regression; Time series analysis.; Mathematics and Statistics;

    Sammanfattning : In recent years there has been a large increase in available data from the electric grid in Finland. The availability of both operational as well as financial data enables exploration of forecasting energy prices using deep learning techniques. LÄS MER

  5. 4. Electromagnetic Homogenization-simulations of Materials

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Julia Törnqvist; [2019]
    Nyckelord :relative permittivity; electromagnetic simulations; FDTD method; scattering parameters; transmitted electric field; reflected electric field; plane wave; wave guides; percolation;

    Sammanfattning : This thesis aims to determine the distribution of the relative permittivity for random mixtures of material using electromagnetic simulations. The algorithm used in the simulations is the FDTD method which solves Maxwell's equations numerically in the time-domain. LÄS MER

  7. 5. MAC-E-Filter characterization for PTOLEMY : a relic neutrino direct detection experiment

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Carl-Fabian Strid; [2019]
    Nyckelord :particle physics; astroparticle physics; astrophysics; PTOLEMY; relic neutrinos; monte carlo simulation; mac-e-filter; sterile neutrinos; physics beyond the standard model;

    Sammanfattning : The cosmic neutrino background (CNB) can be composed of both active and hypothetical sterileneutrinos. At approximately one second after big bang, neutrinos decoupled from radiationand matter at a temperature of approximately one MeV. LÄS MER
