  1. 6. Nonlinear mode coupling and parametric amplification with superconducting kinetic inductance

    University essay from KTH/Tillämpad fysik

    Author : Daniele Lopriore; [2022]
    Keywords : Quantum technology; microwave engineering; nanofabrication; parametric amplifiers; multimode entanglement; kinetic inductance; Kvantteknologi; mikrovågsteknik; nanotillverkning; parametriska förstärkare; multimodentrassling; kinetisk induktans;

    Abstract : We investigate the resonant characteristics of superconducting meandering nanowires to design a nonlinear kinetic inductance traveling-wave parametric amplifier. The devices are patterned out of 15 nm thick NbTiN films. They consist of a coplanar waveguide, that shrinks into 100 nm wide meandering nanowires. READ MORE

  3. 7. Theory of Time-Dependent Transport and Levitons in Nanowires

    University essay from Lunds universitet/Fasta tillståndets fysik

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

    Abstract : 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. READ MORE

  4. 8. Processing of Sub-micrometer Features for Rear Contact Passivation Layer of Ultrathin Film Solar Cells Using Optical Lithography

    University essay from

    Author : Evelina Roxner; Ronja Olsmats Baumeister; [2019]
    Keywords : nanofabrication; optical lithography; photo lithography; line contacts; microfabrication; rear contact passivation; passivation layer; sub-micrometer features; thin film; ultra-thin film; solar cells; CIGS; aluminiumoxide;

    Abstract : Thin film copper, indium, gallium, selenide (CIGS) solar cells are promising in the field of photovoltaic technology. To reduce material and fabrication cost, as well as increasing electrical properties of the cell, research is ongoing towards ultra-thin film solar cells (absorption layer thickness less than 500 nm).

  5. 9. "Fat" Nanobeam-Waveguide Resonator for Suppressing Spectral Diffusion in InGaAs Quantum Dots

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

    Author : Qinda Guo; [2019]
    Keywords : Physics and Astronomy;

    Abstract : The coherent coupling of photons to solid state emitters is one of the building blocks for future quantum technology. However, one of the main sources for non-perfect or even strongly reduced coherence of the photons is charge noise which introduces energy shifts during or in between the photon emission events.

  6. 10. Evaluation of Atomic Layer Etching Possibility at Lund Nano Lab

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

    Author : Md Sabbir Ahmed Khan; [2016]
    Keywords : Atomic Layer Etching; Nanoimprint lithography; Nanowires; Physics and Astronomy;

    Abstract : In modern electronics, device downscaling demands atomic precision control and Atomic Layer Etching (ALE) can provide this prime capability with minute device damage. ALE, also known as layer-by-layer etching, is a technique of removing atomically thin layers from the surface of materials in a controlled way. READ MORE
