  1. 6. Semiconducting TiO2 for High Performance Ferroelectric Tunnel Junctions

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Erik Wikare; [2022]
    Keywords : Technology and Engineering;

    Abstract : The ferroelectric tunnel junction FTJ is a rather old concept but has recently been in the spotlight for its promising properties in computer memory technology and neuromorphic computing. The device consists of a ferroelectric insulator sandwiched between two electrodes, and by polarisation switching the resistance along the heterostructure can drastically be adjusted. READ MORE

  3. 7. Optimisation of tribology of Alfa Laval separator screw gear systems

    University essay from Luleå tekniska universitet/Maskinelement

    Author : Anurag Singh; [2022]
    Keywords : Screw gears; Tribology; Wear; Lubrication; Materials; Surface; Roughness; Twin disc tribometer;

    Abstract : Gears are machine elements essential for mechanical transmission. Wear of gear teeth can causechanges in their profile geometry, causing vibration, noise, and subsequent gear failure. In this thesisproject, a twin disc tribometer has been used to mimic the actual Alfa Laval separator screw gearsystems. READ MORE

  4. 8. Phase and Interface Design in Potential Earth-Abundant Multi-Component Photocatalysts

    University essay from Lunds universitet/Kemiska institutionen

    Author : David Llorens Rauret; [2022]
    Keywords : Facet control; in-situ TEM; nanoparticle heterostructures; phase transformation; transition metal phosphides; inorganic nanomaterials; Chemistry;

    Abstract : Transition metal phosphides are low-cost, earth-abundant semiconductors with promising properties for photocatalysis, including water-splitting. When combined with other semiconductors or noble metals in nanoparticles, their photocatalytic performance can be drastically enhanced. READ MORE

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

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

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

    Abstract : 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. READ MORE

  6. 10. Template-assisted Electrodeposition and Model Electrodes Studied by Electron Microscopy and High Energy X-ray Diffraction

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Hanna Sjö; [2022]
    Keywords : Physics and Astronomy;

    Abstract : There is a great interest in studying detailed changes at electrode surfaces during electrochemical processes to better understand the electrochemical reactions at the electrode surface-liquid interface and improve the electrode efficiency. The Au(110) surface has a known (1$\times$2) missing row reconstruction in vacuum conditions, which can change into higher-order (1$\times$3), (1$\times$5), and (1$\times$7) depending on environment.
