  1. 16. Investigating the use of Semiconductor Nanowires for Neural Networks

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

    Författare :Alfredo Serafini; [2022]
    Nyckelord :FDTD method and simulation; optical broadcasting neural network; optical communication of nanowires; sub-wavelength absorption.; Physics and Astronomy;

    Sammanfattning : In this work, we intend to employ nanowires for the realisation of an artificial neuron which can be used to design a neural network that will guide the new generation of non-von Neumann architectures such as Neuromorphic Computing. Possible applications are strongly related to Neuromorphic architectures and artificial intelligence, such as high-performance computers, robotics hardware and autonomous drones. LÄS MER

  3. 17. Template-assisted Electrodeposition and Model Electrodes Studied by Electron Microscopy and High Energy X-ray Diffraction

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

    Författare :Hanna Sjö; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : There is a great interest in studying detailed changes at electrode surfaces during electrochemical processes to better understand the electrochemical reactions at the electrode surface-liquid interface and improve the electrode efficiency. The Au(110) surface has a known (1$\times$2) missing row reconstruction in vacuum conditions, which can change into higher-order (1$\times$3), (1$\times$5), and (1$\times$7) depending on environment.

  4. 18. Towards a Cooper pair splitter in InAs nanowires with crystal-phase defined quantum dots

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Lunds Tekniska Högskola

    Författare :Louise Olausson; [2022]
    Nyckelord :Cooper pair splitter; quantum dot; nanowire; superconductivity; InAs; crystal-phase; Physics and Astronomy;

    Sammanfattning : Cooper pair splitting (CPS) is a process in which the two spin-entangled electrons of a Cooper pair in a superconductor are split into two spatially separated electrons. If the separated electrons are still entangled, CPS can be studied to increase the knowledge of non-locality in quantum systems. LÄS MER

  5. 19. Quasicrystal nanowires in SNS-junctions

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :Anna Sandberg; [2022]
    Nyckelord :quasicrystal; Fibonacci quasicrystal; superconductivity; SNS-junction; Josephson junction; proximity effect; Josephson current; Bogoliubov-de Gennes method;

    Sammanfattning : Quasicrystals are systems that are ordered but not periodic. They do however still have long-range order and well-defined diffraction peaks. This leads to interesting properties, like critical states which are neither extended nor localized, and to topological invariants and edge states. LÄS MER

  7. 20. Fabrication Development of InAs-Pb Nanodevices

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Bo Rasmus Edholm; [2022]
    Nyckelord :Nanofabrication; Qubit; InAs; SAG; Nanowire; Lithography; EBL;

    Sammanfattning : Research groups around the world are looking to develop a qubit protected from decoherence for achieving quantum advantage in computations. This would have huge impact on the modern world. The applications are many from drug development to cryptography and many more  elds. LÄS MER
