  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. Laminated HZO on InAs: A study of as-deposited ferroelectricity

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

    Författare :André Andersen; [2022]
    Nyckelord :Ferroelectricity; HZO; InAs; III V; As-deposited ferroelectricity; BEOL; Nanoelectronics; Nanoprocessing; Nanotechnology; ALD; MOSCAP; Memory Technology; Technology and Engineering;

    Sammanfattning : As the limits of transistor feature size scaling is reaching its saturation, new innovations are needed to prevent performance loss. High performance transistors on the III/V semiconductor platform implemented with ferroelectric oxides might in the future satisfy this demand. LÄS MER

  4. 3. Analysis of condition for ALD deposition of ferroelectric HZO

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

    Författare :Teodor Qvint; [2022]
    Nyckelord :HZO; Ferro; ALD; Temperature; Purge time; Technology and Engineering;

    Sammanfattning : Deposition of ferroelectric hafnium zirconium oxide (HZO) on semiconductor samples with Atomic Layer Deposition (ALD) has proven to be a viable method of production. But while the physical processes of ALD deposition is relatively well know, there exists some gaps in knowledge about different parameters for the ALD and the resulting depositions. LÄS MER

  5. 4. Factors governing marble lightness in peripheral alteration haloes around carbonate-hosted Zn-Pb-Ag-(Cu-Au) deposits, Garpenberg, Sweden

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Marcus Eriksson; [2020]
    Nyckelord :Carbonate; Zn; Pb; Ag; Cu; Au; Alteration haloes; marble; lightness; Bergslagen; Garpenberg;

    Sammanfattning : A Master thesis about the Garpenberg deposit located in Bergslagen, a lithotectonic domain, with a mining history that might date back as far as 350 BC. Marble- and skarn-hosted sulfide deposits are found in the area, which creates the opportunity to mine both limestone and sulfidic ore in a single mine. LÄS MER

  7. 5. Joint Calibration of a Cladding Oxidation and a Hydrogen Pick-up Model for Westinghouse Electric Sweden AB

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Joakim Nyman; [2020]
    Nyckelord :Marcov Chain Monte Carlo; Surrogate Model; Gaussian Process; Marginal Likelihood Optimisation; The Margin Method; Dakota; Transuranus; Calibration; Machine Learning; Software Coupling;

    Sammanfattning : Knowledge regarding a nuclear power plants potential and limitations is of utmost importance when working in the nuclear field. One way to extend the knowledge is using fuel performance codes that to its best ability mimics the real-world phenomena. LÄS MER
