  1. 1. Design and Modeling of InxGa(1−x)As/InP based Nanosheet Field Effect Transistors for High Frequency Applications

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

    Författare :Hanyu Liu; Xi Chen; [2023]
    Nyckelord :nanosheet NS ; gate-all-around GAA ; channel release; parasitic channel; MATLAB; COMSOL; technology node; Technology and Engineering;

    Sammanfattning : The advancement of CMOS technology has been fueled by the need to satisfy Moore’s law by shrinking transistors to progressively smaller sizes and increasing the transistor density per unit area [1]. The dimension of the state-of-the-art MOSFET is now down to a few nanometers. LÄS MER

  3. 2. Radiation Shielding Simulations for Small Satellites on Geostationary Transfer Orbit

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Anton Fetzer; [2022]
    Nyckelord :GTO; Foresail-2; CubeSat; Radiation Shielding; Geant4; Radiation Belts; GTO; Foresail-2; CubeSat; säteilysuojaus; Geant4; säteilyvyöhyke;

    Sammanfattning : The emergence of small and affordable satellites has led to rapid growth in the number of launched satellites over the past two decades. To save costs, small satellites often use mass-produced electronic components not explicitly designed for the radiation environment of space, which reduces reliability and makes them unsuitable for higher orbits.

  4. 3. Investigation of the Magnetic- and Electron Transport Properties of Fe/MgO Superlattices

    Kandidat-uppsats, Uppsala universitet/Materialfysik

    Författare :Ali Rostom; David Holmgren; [2022]
    Nyckelord :Fe MgO superlatice; interlayer exchange coupling; Van der Pauw; electronic transport; magnetic field; resistive properties; 3D memory storage;

    Sammanfattning : Anti-ferromagnetic interlayer exchange coupling between iron layers in Fe/MgO superlatices have recently been of interest among researchers for its potential application in 3D memory storage in computers (hard drives) and in the research field of spintronics. Thinfilms and bi-layers between the 10-100 ångström range in thicknesses were analyzed for its resistive properties during different conditions. LÄS MER

  5. 4. Fabrication and Characterisation of iontronic micropipette

    Master-uppsats, Linköpings universitet/Laboratoriet för organisk elektronik; Linköpings universitet/Tekniska fakulteten

    Författare :Henrik Hamrefors; [2022]
    Nyckelord :Iontronic drug delivery; Iontronic micropipette; Ion exchange membrane; AMPSA; A-HPG; Fabrication; Characterisation; Teknisk biologi; Teknisk biologi;

    Sammanfattning : The biological translation between biological and electrical signals have inspired scientists over the last decade and has opened new way of therapeutics. The group of Bioelectronics at the Laboratory of organic electronics (LOE) develops systems that utilizes this translation to reduce the gap between electronics and biology. LÄS MER

  7. 5. Modelling of Fluid Flow and Contaminant Transport in Fractured Rock : Case Study

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Ebba Pegestam; [2022]
    Nyckelord :Contaminant transport; Discrete Fracture Network; Geology; Geohydrology; Groundwater transport; Fracture; Drinking water; Contamination; Föroreningar; flödestransport; spricknätverk; geologi; geohydrologi; grundvattentransport; sprickor; dricksvatten;

    Sammanfattning : Drinking water contamination is a big concern in Sweden and is commonly traced back to being waste from former manufacturing industrial sites. Pollutants in the topsoil can be remediated by several techniques, such as decontamination or excavation but the toxins already enclosed in the bedrock cannot be treated the same and is harder to track possible contaminant pathways.
