  1. 1. 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).

  2. 2. "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.

  3. 3. 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

  4. 4. Cooper-Pair Decoherence in SNS Hybrid Structure

    University essay from Umeå universitet/Institutionen för fysik

    Author : Sareh Shafiei; [2014]
    Keywords : ;

    Abstract : The Laws of quantum mechanics control the behavior of electrons in nanoscale devices and nanostructures. Quantum coherence of electrons can appear in different experiments. In this work we used SNS (Superconductor-Normal-Superconductor) structures in order to experimentally and theoretically study and investigate the effect of quantum decoherence. READ MORE

  5. 5. Cryogenic Etching of the Electroplating Mold for Improved Zone Plate Lenses

    University essay from KTH/Tillämpad fysik

    Author : Daniel Larsson; [2010]
    Keywords : etching; plasma etching; zone plate; x-ray; nanofabrication; sidewall passivation; cryo; cryogenic; undercut;

    Abstract : The fabrication of zone plate lenses that are used for focusing X-rays relies on nanofabrication techniques such as e-beam lithography, reactive ion etching, and electroplating. The circular grating-like zone plate pattern can have a smallest half-period, a so-called zone width, of down to 20 nm while it also needs to have a height that is 5 to 10 times the zone width to have good diffraction efficiency.
