  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. Flashlamp Annealing for Improved Ferroelectric Junctions

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

    Författare :Theodor Blom; [2023]
    Nyckelord :Flashlamp annealing; ferroelectricity; hafnia oxide; III-V semiconductor; thermal annealing; device performance; Technology and Engineering;

    Sammanfattning : The effects of flashlamp annealing (FLA) on the quality of ferroelectric HfxZr1–xO2 (HZO) interfaces, integrated on InAs substrates, are evaluated. For the integration of ferroelectric HZO on III-V semiconductors the crystallization via rapid thermal processing (RTP) can severely degrade the HZO/III-V interface. LÄS MER

  4. 3. Growth and Characterization of Ferroelectric Lanthanum-Doped Hafnia

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Harald Havir; [2020]
    Nyckelord :Ferroelectricity; Lanthanum-doped Hafnia; ALD; Science General;

    Sammanfattning : Hafnia-based ferroelectrics show great promise as future nonvolatile memory devices, however, their issues regarding device inconsistency across their lifetime, coupled with the relatively short total lifetime, makes these devices only theoretical as of now. In this thesis, an ALD deposition recipe for lanthanum oxide deposition was created. LÄS MER

  5. 4. Microbial processes and volatile metabolites in cheese : detection of bacteria using an electronic nose

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik; Örebro universitet/Restaurang- och hotellhögskolan

    Författare :Magnus Westling; [2015]
    Nyckelord :Enterobacteriaceae; Lactococcus; electronic nose;

    Sammanfattning : Cheese is a fermented product in which bacteria contribute to different flavours and textures. In order to understand the microbial processes in cheese, it is necessary to not only look at the genomic information in bacteria. The metabolome consists of a complete collection of metabolites in a biological sample. LÄS MER
