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

    University essay from Lunds universitet/Centrum för analys och syntes

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

    Abstract : 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. READ MORE

  3. 2. Photoluminescence Mapping of Erbium Doped Lithium Niobate

    University essay from KTH/Tillämpad fysik

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

    Abstract : 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.

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

    University essay from KTH/Tillämpad fysik

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

    Abstract : 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. READ MORE

  5. 4. Alignment of Image Sensor using Piezoelectric Crystals

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik
