  1. 1. Construction of a scanning confocal microscope for Quantum Dot mapping at telecom wavelength

    University essay from KTH/Tillämpad fysik

    Author : Alexandros Bampis; [2023]
    Keywords : Nanophotonics; Quantum Dot Positioning; Photoluminescence Mapping; Scanning Microscope; Nanofotonik; Positionering av kvantprickar; Fotoluminescenskartläggning; Skanningsmikroskop;

    Abstract : Future commercial applications making use of non-classical light sources require bright quantum emitters. Such emitters can be achieved by embedding self-assembled, optically active semiconductor quantum dots (QDs) in centered photonic structures. READ MORE

  3. 2. First Principles Studies Of 2D Magnets

    University essay from

    Author : Yahya Fayazi; Linus Jacobsson; Folke Gustafsson; [2022]
    Keywords : 2D material; ab initio; magnet; Quantum Espresso; Density Functional Theory; DFT; CrCl3; CrBr3; CrI3; 2D material; 2 dimensionella material; två dimensionella material;

    Abstract : The aim of this project is to examine the electric and magneticproperties of three monolayer chromium trihalides when doped withdifferent transitions metals, that is CrXY_6, where X=(Mn,Fe,Co,Ni,V)and Y=(Cl,Br,I). The calculations were made using the software programQuantum Espresso that used density functional theory to solveSchrödinger’s equation. READ MORE

  4. 3. 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.

    Abstract : This master’s thesis focuses on investigating the electronic properties of the superconducting spinel compound LiTi2O4 by means of computational and experimental effort. The title compound has been extensively studied in the past years, being the only known superconducting spinel oxide with relatively high Tc = 11.5 K. READ MORE

  6. 5. First Principle Calculations & Inelastic Neutron Scattering on the Single-Crystalline Superconductor LaPt2Si2

    University essay from KTH/Materialvetenskap

    Author : Mazza Federico; [2020]
    Keywords : Superconductivity; LaPt2Si2; Inelastic Neutron Scattering; Charge Density Wave; Band Structure Calculations; DFT; SNIC; J-PARC; Supraledning; LaPt2Si2; neutronspridning; neutronspektroskopi; Bandberäkningar; DFT; J-PARC;

    Abstract : This work presents a comprehensive study on single crystalline LaPt2Si2, in which superconductivity and a charge density wave (CDW) coexist. The usage of density functional theory (DFT) modeling and Inelastic Neutron Scattering has been the primary form of investigation, in order to determine all the characteristic features of the sample taken under consideration.
