  1. 31. Micromagnetic Study of Current Induced Domain Wall Motion for Spintronic Synapses

    University essay from Uppsala universitet/Energimaterialens fysik

    Author : Dimitrios-Petros Petropoulos; [2021]
    Keywords : computational physics; micromagnetism; micromagnetic simulations; Mumax3; current induced domain wall motion; domain wall driving; spin current; spin transfer torque; synapse; memristor; Neuromorphic computing; spintronic; brain inspired computing; Permalloy; nanowire; nanostrip; notches;

    Abstract : Neuromorphic computing applications could be made faster and more power efficient by emulating the function of a biological synapse. Non-conventional spintronic devices have been proposed that demonstrate synaptic behavior through domain wall (DW) driving. READ MORE

  3. 32. Towards the detection of single photons in the mid-infrared

    University essay from KTH/Tillämpad fysik

    Author : Bruno Lopez; [2021]
    Keywords : mid-infrared; single-photon; superconducting; nanowire; nanotechnology; quantum technologies; imaging; mitten av infraröd; enfoton; supraledande; nanotråd; nanoteknik; kvantteknologi; avbildning;

    Abstract : In this project, the fabrication of single-photon detectors based on superconducting nanowires is presented, with great focus on extending their operation range to the mid infrared. In particular, Niobium Titanium Nitride (NbTiN) and Molybdenum Silicide (MoSi), superconducting materials with different properties, are presented, studied and used as fabrication platforms.

  4. 33. Investigations of p-type quantum dots in GaSb nanowires

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : In-Pyo Yeo; [2021]
    Keywords : Physics and Astronomy;

    Abstract : The purpose of this project is to investigate hole transport in p-type quantum dots formed in GaSb nanowire and operating as single hole transistors. The individual and controlled hole-spin confinement in such system yields a variety of proposed applications for spintronics or quantum computation. READ MORE

  5. 34. Live 3D imaging quantum LiDAR

    University essay from KTH/Tillämpad fysik

    Author : Theodor Staffas; [2021]
    Keywords : lidar; otdr; snspd; lidar; otdr; snspd;

    Abstract : In this thesis, I demonstrate a single­photon Light Detection And Ranging, (LiDAR)system operating at 1550 nm capable of reconstructing 3D environments live withmm resolution at a rate of 400 points per second using eye­safe laser pulses. Thesystem was built using off­-the-­shelf optical components and analysis was performedusing open-­source software. READ MORE

  6. 35. Characterization of InAs-Al semiconductor-superconductor hybrid devices

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Markus Aspegren; [2020]
    Keywords : quantum dot; superconductivity; quantum transport; josephson junction; spectroscopy; yu-shiba-rusinov; hybrid devices; sub-gap states; quantum computer; majorana bound state; bogoliubov quasiparticle; Physics and Astronomy;

    Abstract : In this thesis we study charge and spin transport through InAs-Al nanowire superconductor-semiconductor hybrid devices. We focus on assessing the quality of the InAs-Al contact interface when using a weak HCl acid to wet-etch the nanowire surface prior to metal evaporation. READ MORE
