  1. 6. Semiconducting TiO2 for High Performance Ferroelectric Tunnel Junctions

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Erik Wikare; [2022]
    Keywords : Technology and Engineering;

    Abstract : The ferroelectric tunnel junction FTJ is a rather old concept but has recently been in the spotlight for its promising properties in computer memory technology and neuromorphic computing. The device consists of a ferroelectric insulator sandwiched between two electrodes, and by polarisation switching the resistance along the heterostructure can drastically be adjusted. READ MORE

  3. 7. Influence of Superconducting Order Parameter on Quasi-Particle Interference

    University essay from Uppsala universitet/Materialfysik

    Author : Siri Alva Berge; [2022]
    Keywords : ;

    Abstract : Superconductors are important to study due to their many applications. Superconductivityarises when electron pairs, so-called Cooper pairs, form in the material.To understand the mechanism behind the formation of the Cooper pairs, the pairingsymmetry, described by the order parameter, must be found.

  4. 8. Quantum Simulation of Quantum Effects in Sub-10-nm Transistor Technologies

    University essay from Uppsala universitet/Materialteori

    Author : Anders Winka; [2022]
    Keywords : Transistor Modeling; Quantum Transport; QTBM; Block Cyclic Reduction; Quantum Computing; Quantum Annealer;

    Abstract : In this master thesis, a 2D device simulator run on a hybrid classical-quantum computer was developed. The simulator was developed to treat statistical quantum effects such as quantum tunneling and quantum confinement in nanoscale transistors. READ MORE

  5. 9. The impact of noice pollution and vibrations on nearby buildings : How is the school Kulturama affected by noise and vibrations from the 'nya tunnelbana' project?

    University essay from KTH/Byggteknik och design

    Author : Hadil Jawad; Aren Nabatyan; [2021]
    Keywords : Noice pollution; vibrations; metro; nya tunnelbana project; noice absorbents; Buller; vibrationer; stomljud; luftburet ljud; nya tunnelbana projekt; absorbenter;

    Abstract : To meet the needs of the growing city of Stockholm, a large-scale project to expand the subway has been initiated. The tunneling involved in the project causes several disturbances, in terms of vibration and noise pollution, on the surroundings. This is problematic as vibration and noise pollution has been shown to have a negative health impact. READ MORE

  6. 10. Primordial Gravitational Waves and ultra-light Dark Matter in a complex singlet extended Standard Model

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Sara Wildenor; [2021]
    Keywords : theoretical physics; gravitational waves; dark matter; complex singlet extended standard model; LISA; BBO; DECIGO; Physics and Astronomy;

    Abstract : In this thesis, the consequences of extending the internal symmetries of the standard model with a complex singlet scalar field, are investigated in terms of dark matter phenomenology and the possibility of primordial gravitational wave detection utilizing space based laser interferometry. The scalar potential of the model is constructed with a Z2 symmetry, which allows for the retainment of a linear and a quadratic coupling parameter, as well as a stable dark matter candidate, and an additional non-zero vacuum expectation value for the real component of the scalar field.
