  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. Investigation of Resistive Random Access Memory for 1T1R Nanowire Array Integration

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Orestes Theodoridis; [2020]
    Nyckelord :RRAM; Nanowire; Memory Technology; Nanoelectronics; Nanoscience; Physics and Astronomy;

    Sammanfattning : As modern electronics have started to reach its physical scaling limits, novel architectures and physics is needed to meet future demands. Oxide-based Resistive Random Access Memory (RRAM) is a new emerging technology that uses filament formation and rupture in thin oxides to generate resistive switching. LÄS MER

  4. 3. Fabrication and characterization of novel nano-magnets

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Författare :Louise Lifvenborg; [2020]
    Nyckelord :nanotechnology; nano-magnets; magnetism; Master s Programme in Materials Engineering; Q; lithography;

    Sammanfattning : Magnetic data storing has been of great interest since 1950 when the first magnetic hard drive was fabricated. A lot has happened since then, but there is still a need for smaller and cheaper devices.  One way to achieve this is by creating nano-sized ferromagnetic areas in a thin film at room temperature, or nano-magnets.

  5. 4. Design and Simulation of Terahertz Antenna for Spintronic Applications

    Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Nils Eivarsson; Malin Bohman; Emil Grosfilley; Axel Lundberg; [2020]
    Nyckelord :spintronics; terahertz; THz; antenna; simulation; COMSOL multiphysics;

    Sammanfattning : Spintronics is a spin-electronic field where the electron spinangular momentum, in conjunction with charge, is used to read andwrite information in magnetic sensors and logic circuits, e.g. hard disk drive (HDD), magnetic random access memory (MRAM) and broadband TeraHertz (THz) emitters.

  7. 5. The Magnetic Characterization of Iron-Chrome nanoparticle

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

    Författare :Angga Virdian; [2018]
    Nyckelord :Nanomagnetism; Nanoparticle; Physics and Astronomy;

    Sammanfattning : In this thesis, the intrinsic magnetic characteristic of 10 nm FeCr oxide nanoparticles is studied. The nanoparticles is produced using the method of Spark discharge generation. Scanning electron microscope (SEM) is used to characterize the size distribution and coverage of deposited particle. LÄS MER
