  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. Neutron Veto Inefficiency Studies with FLUKA for the LDMX Hadronic Calorimeter

    Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Jaida Raffelsberger; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Dark matter accounts for about 85% of all matter in the Universe, yet its particle nature remains unknown. The Light Dark Matter eXperiment (LDMX) is a proposed fixed-target missing-momentum experiment that intends to probe the predominantly experimentally uncharted MeV-GeV mass range for "light dark matter".

  4. 3. Exploring the Feasibility of Using Fire Dynamics Simulator to Improve the Calculation of the Wildfire Available Safe Egress Time

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Alfred El Haddad; [2023]
    Nyckelord :Wildfire; Trigger buffer; WUI; WASET; FDS; QGIS; Level set; WUI evacuation.; Technology and Engineering;

    Sammanfattning : Wildland-Urban Interface (WUI) fires pose a significant threat to public safety and property in areas where urban development encroaches upon natural landscapes. This thesis aims to investigate the effect of smoke from a WUI fire on the tenability conditions of a small village and to establish a worst-case-scenario trigger boundary around it as an improved basis for the WUI available safe egress time (WASET).

  5. 4. Upgrade of the LHCb simulation framework with advanced particle event generators

    Master-uppsats, KTH/Fysik

    Författare :Ruben Pozzi; [2023]
    Nyckelord :;

    Sammanfattning : The LHCb experiment is one of the main detectors in function at the Large Hadron Collider (LHC) at CERN. In order to interpret the data recorded by the detector, Monte Carlo (MC) samples are used as a way to validate and test theories by comparison with the experimental data. LÄS MER

  7. 5. Fabrication and Characterization of Quantum-well Field Effect Transistor

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

    Författare :Yang Fu; [2022]
    Nyckelord :quantum-well field-effect transistor; InGaAs; subthreshold swing; sheet resistance; contact resistance; electron mobility; Post Metallization Annealing; electrostatic control; Physics and Astronomy;

    Sammanfattning : The project aims to optimize the design and fabrication of InGaAs quantum-well field-effect transistor (QW-FET) by investigating transfer and output characteristics of the QW-FET. This work found a lower source/drain contact resistance solution starting with fabricating micrometer-level gate length transistors. LÄS MER
