  1. 21. Simulating the Effect of Spatial Potential Variation in Nanodevices with the NEGF Method

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

    Författare :Markus Berthilsson; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : In this master thesis nanowires have been simulated to study the effect of spatial imperfections in the nanowires. This spatial imper- fection took the form of potential fluctuations in the conduction band across the wire. LÄS MER

  2. 22. Surface Functionalization of Nanowires Using Silane-PEG Compounds

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Hedvig Ekfors Elvin; [2022]
    Nyckelord :Functionalization; Nanowires; Silanization; Surface Chemistry; Materials Chemistry; Chemistry;

    Sammanfattning : Introduction: GaP nanowires were functionalized using silane-PEG-NH2 and compared with cellulose acetate, PAcrAm™-g-(PMOXA, amine, silane) and a non-functionalized reference sample. Functionalization would allow strong, covalent anchoring of antibodies instead of adsorption. LÄS MER

  3. 23. Carbon-coated Lead Halide Perovskite Quantum Dots and Copper(I)Iodide Coated Copper Nanowire Electrodes for Flexible Solar Cells

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Albin Andersson; [2022]
    Nyckelord :Nanotechnology; solar cells; perovskite; quantum dots; nanowire; thin film electrodes; nanoteknologi; solceller; perovskit; kvantprickar; nanotrådar;

    Sammanfattning : Lead Halide Perovskite is emerging quickly as a promising material for the future solar cellsthanks to their inherent good optoelectrical properties along with their cheap and facile fabri-cation. However, their main drawback before commercialization is their weak stability. LÄS MER

  4. 24. Towards laser fabrication of soft neural electrodes

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

    Författare :John Schill; [2022]
    Nyckelord :Stretchable electrodes; UV-laser ablation; Silver nanowires; 355 nanoseconds laser; electrode patterning; Teknisk biologi; Teknisk biologi;

    Sammanfattning : Electronic devices define our everyday lives. They are often large, rigid, and brittle. Modern medical science has come so far as to start using miniature electronic devices to monitor many types of diseases. LÄS MER

  5. 25. Nonlinear mode coupling and parametric amplification with superconducting kinetic inductance

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Daniele Lopriore; [2022]
    Nyckelord :Quantum technology; microwave engineering; nanofabrication; parametric amplifiers; multimode entanglement; kinetic inductance; Kvantteknologi; mikrovågsteknik; nanotillverkning; parametriska förstärkare; multimodentrassling; kinetisk induktans;

    Sammanfattning : We investigate the resonant characteristics of superconducting meandering nanowires to design a nonlinear kinetic inductance traveling-wave parametric amplifier. The devices are patterned out of 15 nm thick NbTiN films. They consist of a coplanar waveguide, that shrinks into 100 nm wide meandering nanowires. LÄS MER
