1. Structural analysis of HZO thin film and electrode using X-ray diffraction
Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenSammanfattning : 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
2. Tuning Photovoltaic Properties of Two-dimensional Molybdenum Disulfide by Alloying: An ab initio study
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Addressing the urgent need for innovative energy solutions amidst increasing environmental concerns, the focus on photovoltaic solar cells is intensifying. Currently limited by the Shockley-Queisser limit, conventional silicon-based solar cells offer a maximum power conversion efficiency of 32%. LÄS MER
3. Åldring av högtranslucent zirkoniumdioxid (3Y-TZP) i munmiljö jämfört med artificiella åldringsmetoder. En pilotstudie. : Aging of high translucent zirconium dioxide (3Y-TZP) in the oral environment compared to artificial aging methods. A pilot study.
Kandidat-uppsats, Malmö universitet/Odontologiska fakulteten (OD)Sammanfattning : Sammanfattning Syfte Syftet med pilotstudien var att utvärdera hur kristallfaserna i högtranslucent zirkoniumdioxid (3Y-TZP) påverkas av åldring i munmiljö (in-vivo-metod) och in-vitro-metoder för artificiellt åldrande: vattenförvaring, termocykling och autoklavering. Material och metod Totalt framställdes 16 provkroppar av högtranslucent zirkoniumdioxid (3Y-TZP) med slutmått på 1 mm i tjocklek och 5 mm i diameter. LÄS MER
4. Laminated HZO on InAs: A study of as-deposited ferroelectricity
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : 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
5. Metal-Organic Frameworks for Carbon Dioxide Capture : Using Sustainable Synthesis Routes
Master-uppsats, Uppsala universitet/Institutionen för materialvetenskapSammanfattning : Globally the combustion of fossil fuels has increased to a greater extent. Carbon dioxide (CO2) a major greenhouse gas isa by-product of such combustion practices. LÄS MER
