  1. 1. Från diamant till kristall En undersökning av annonsens roll i Swarovskis omprofilering

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvetenskaper

    Författare :Annie Salius Koka; [2023-05-31]
    Nyckelord :Omprofilering; varumärkesprofil; varumärkesidentitet;

    Sammanfattning : In recent years many brands have changed their looks and entire brand identities to keep up with the ever changing trends and demands. This paper will focus on the Austrian brand Swarovski mostly known for their crystal figurines and jewelry, who in 2021 underwent a total rebranding. LÄS MER

  3. 2. In-Situ Investigation of Particle Assisted GaSb Nucleation Using Environmental TEM

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

    Författare :Aidas Urbonavicius; [2023]
    Nyckelord :ETEM; Nucleation; GaSb; Nanowires; Materials chemistry; Technology and Engineering; Chemistry;

    Sammanfattning : III-V semiconductor material based nanowires have been extensively studied and shown to be a very exciting building block for future electronics. Material systems such as GaSb show a lot of promise in optoelectric and thermoelectric generation applications because of its high electron mobility and small bandgap. LÄS MER

  4. 3. Photoluminescence Mapping of Erbium Doped Lithium Niobate

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Chuanshi Xie; [2023]
    Nyckelord :Automotive mapping; Erbium emitters; Ion implantation; Lithium niobate on insulator; photoluminescence microscopy; Automatisk kartläggning; Erbium fotonemitterare; Jonimplantation; Litiumniobat på isolator; fotoluminiscensmikroskopi.;

    Sammanfattning : Lithium niobate (LiNbO3) is a human-made crystalline which is widely used in modern photonics due to its useful properties. In recent years, there has been significant progress in the development of lithium niobate on insulator (LNOI) technology, realizing a fully functional photonic integrated circuits, thanks to its capabilities in both electro-optics and second-order optical nonlinearity.

  5. 4. Modulation of the optical properties of quantum dots by surface acoustic waves

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Tanguy Schetelat; [2023]
    Nyckelord :Nanophotonics; Quantum dots; Surface acoustic waves; Interdigital tansducers; Optomechanical coupling; Nanofotonik; Kvantprickar; Akustika yt-vågor; Interdigital tansducers; Optomekanisk koppling;

    Sammanfattning : Semiconductor quantum dots (QDs) are considered to be a crucial part of future quantum technologies due to their enormous potential as efficient sources of single and indistinguishable photons. Single photons are necessary to transport quantum information over large distances through the existing global fibre optic network. LÄS MER

  7. 5. Alignment of Image Sensor using Piezoelectric Crystals

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Julia Jakobsson; Reem Chahrour Muhieddine; [2023]
    Nyckelord :piezo; piezoelectric; crystal; piezoelectric crystal; piezoelektrisk; kristall; piezoelektrisk kristall; camera; kamera; focus; fokus; Axis; Axis Communications; alignment; justering; prototyp; prototype; algorithm; algoritm; Technology and Engineering;

    Sammanfattning : The use of piezoelectric crystals as a way to achieve automatic alignment of an image sensor in a camera was investigated in collaboration with Axis Communications AB. Piezoelectric crystals can be created into different configurations, piezoelectric stacks being one of the simpler ones. LÄS MER
