1. 6. 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. 7. Measuring copper abundances in the Galactic Bulge

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

   Författare :Nikolei Höglinger; [2024]
   Nyckelord :Copper; Galaxy: abundances; Galaxy: bulge; Chemical Evolution; Physics and Astronomy;

   Sammanfattning : Context: The chemical evolution of Cu in the Galactic bulge have been studied in a few studies using red giant branch stars, but the ages of individual red giant stars are difficult to determine. In addition, the bulge has been a challenging region of the Milky Way galaxy to obtain high-resolution spectra of stars, except when observing through certain few small fields into the bulge that are known to have low extinction.

4. 8. Prospects for a Free Electron Laser at the FemtoMAX Beamline

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

   Författare :Johan Holmberg; [2024]
   Nyckelord :Free Electron Lasers; FEL; synchrotron radiation; MAX IV; FemtoMAX; GENESIS 1.3; XFEL; X-rays; soft X-rays; Physics and Astronomy;

   Sammanfattning : A Free Electron Laser (FEL), is a device that generates extremely coherent and brilliant radiation using electrons accelerated to relativistic velocities in a particle accelerator. The process utilises similar equipment to what is used at a synchrotron source like MAX IV, but in addition there is an interaction between the relativistic electron beam and the generated radiation to achieve an exponential growth in radiation intensity.

5. 9. Greenhouse gas emissions from peat soil thawing in spring : a comparison between fertilized and unfertilized soil

   Master-uppsats, SLU/Dept. of Soil and Environment

   Författare :Fanny Otterlin Karlsson; [2024]
   Nyckelord :agricultural soil; carbon dioxide; freeze-thaw cycles; nitrous oxide; soil temperature; water content;

   Sammanfattning : Peat soils drained for agriculture and forestry contribute to a significant amount of greenhouse gas emissions. Nitrous oxide is a greenhouse gas with high warming potential and agriculture in general accounts for about 70 % of nitrous oxide emissions. LÄS MER

7. 10. Penningpolitik och ekonomisk ojämlikhet : Finns ett kausalt samband mellan styrränta och ekonomisk ojämlikhet?

   Kandidat-uppsats, Uppsala universitet/Nationalekonomiska institutionen

   Författare :Felicia Sjöström; [2024]
   Nyckelord :Economic inequality; Policy rate; Gini coefficient; Income distribution; Wealth distribution; Percentiles;

   Sammanfattning : Recent decades, growing trends in economic inequality have been observed across the world. While the underlying causes are many, there is a recent and growing field of research discussing the potential effects that changes in policy rates and other kinds of economic policy may have on economic inequality.
