  1. 6. Constructing and commissioning of a Multi-Grid neutron detector prototype for the European Spallation Source

    Master-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB

    Författare :Rebecka Wahlén; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : A prototype of a novel 10B-based neutron detector called the Multi-Grid detector has been constructed, tested and commissioned for the European Spallation Source (ESS). The detector is constructed after the specifications set by the CSPEC instrument at ESS and is therefore called the CSPEC Multi-Grid detector. LÄS MER

  3. 7. Projections for charm balance functions in heavy-ion collisions

    Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Tilde Bonnevier Wallstedt; [2022]
    Nyckelord :Heavy-ion physics; quark-gluon plasma; QGP; balance function; charm quark; Physics and Astronomy;

    Sammanfattning : In this thesis, pp collisions were simulated using PYTHIA. D+ D- and D0 D0bar balance functions were created in order to contribute with a reference point for future balance functions measured in real data from Pb-Pb collisions. LÄS MER

  4. 8. Theory of Time-Dependent Transport and Levitons in Nanowires

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik

    Författare :Jakob Westerberg; [2021]
    Nyckelord :leviton; Tkwant; tight-binding model; solid-state physics; time-dependent transport; scattering theory; quantum mechanics; computer simulation; nanowire; Physics and Astronomy;

    Sammanfattning : An interesting type of quasi-particles in solid-state materials are the so-called levitons. These are single- electron excitations above the Fermi-level that do not produce any hole states when carrying an integer multiple of the elementary charge. LÄS MER

  5. 9. Hall Measurements at Cryogenic Temperatures

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

    Författare :Viktor Wallén; [2021]
    Nyckelord :Hall measurement; Hall effect; Cryoelectronics; Cryogenics; Subthreshold slope; Subthreshold swing; Mobility; Carrier Concentration; Resistivity; Boltzmann limit; van der Pauw measurement; Semiconductor; Nanoelectronics; Nanophysics; Solid state physics; Technology and Engineering;

    Sammanfattning : Kryoelektronik är av allt större intresse inom många tillämpningar, exempelvis för utveckling av kvantdatorer. Detta arbete vill därför undersöka de effekter kryogeniska temperaturer (under 10 K) har på halvledarkomponenter och deras elektriska egenskaper. Särskilt intressant är effekten på subthreshold swing (SS). LÄS MER

  7. 10. Detailed Balance in Quantum Dot Tunneling

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

    Författare :Martin Plate; [2021]
    Nyckelord :thermodynamics; quantum dot; quantum tunneling; physics; solid state physics; nanoscience; Physics and Astronomy;

    Sammanfattning : Previously recorded data of electron tunneling in and out of a quantum dot (QD) is used to extract knowledge of the state of the system. Using the detailed balance of the system, it is shown that information about the electron temperature in the lead Te, as well as knowledge about the degeneracies of the states in a quantum dot can be obtained from measurements of the tunneling rates in and out of the QD.
