  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. Electron-skyrmion systems, in and out of equilibrium, and isolated or contacted to reservoirs

    Magister-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Emil Adam Jonatan Östberg; [2023]
    Nyckelord :skyrmion; skyrmions; NEGF; freen s function; quantum transport; non-equlibrium; topology; topological charge; skyrmionics; current induced; open system; Physics and Astronomy;

    Sammanfattning : A Kondo lattice skyrmion model in contact with a macroscopic environment is simulated to explore skyrmion dynamics, which is an extension of previous work. The system is simulated using non-equilibrium Green's functions within the generalized Kadanoff-Baym ansatz and the wide band limit. LÄS MER

  4. 3. Agile robotic arm for vertical applications - Evaluation, design and development

    Master-uppsats, Lunds universitet/Maskinelement

    Författare :Rasmus Gren; [2023]
    Nyckelord :Robotic arm development; HKM; Kinematics; Product development; Technology and Engineering;

    Sammanfattning : Existing pick and place robots are either heavy or have a limited workspace for vertical operations. Since there is no robot today that are both light and have a good vertical workspace, this leads to a gap in the market. LÄS MER

  5. 4. Optimering av hjulprofil till en spårgående fordonsprototyp

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Olof Skagerlind; Gabriel Forsling; [2023]
    Nyckelord :Delsbo Electric; Wheel profile; Track vehicle; Train Wheel; Delsbo Electric; hjulprofil; spårfordon; tåghjul;

    Sammanfattning : Hållbara transporter är en viktig faktor för att minska koldioxidutsläppen och bidra till en mer hållbar framtid. Den svenska järnvägen är en viktig del av infrastrukturen och transporterar dagligen hundratusentals människor och stora mängder varor. Transportsektorn förbrukar nu cirka en tredjedel av den totala energin i världen. LÄS MER

  7. 5. Theoretical examination of temperature distribution in an electrical furnace by the study of transient heat conduction effects

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Materialteori

    Författare :Judith Bösenecker; [2023]
    Nyckelord :sintering; heat transfer; transient heat conduction; sintring; värmeöverföring; transient värmeledning;

    Sammanfattning : The company Kanthal produces electric heating elements that require high temperature treatment in one production step. In this process step, called sintering, the amount of heat received by the sintered material is in direct correlation to the product’s outcome. LÄS MER
