  1. 1. Design of solvent vapor annealing tool and study of kinetics of selfassembly of block copolymers for nano-lithography

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

    Författare :Chujun Wang; [2020]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Block copolymer lithography is a very promising candidate for nanoscale fabrication and is economically viable. It provides a high resolution, inexpensive, and straightforward approach to nano-size patterning. In this thesis, fundamental concepts and theories of block copolymer lithography are introduced.

  2. 2. Patterning of perovskite thin films for electrical and optical characterisation

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

    Författare :Nils Lamers; [2020]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : While perovskite solar cells have become increasingly more efficient and popular, electrical characterisation of the semiconductor properties of perovskites has been limited due to the instability of the material. In this work, multiple approaches for creating such electrical test structures from perovskites are discussed. LÄS MER

  3. 3. Aspects of Error Quantification and Evaluation in Digital Elevation Models for Glacier Surfaces

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Jip Jan van Zoonen; [2020]
    Nyckelord :Geography; Geographical Information Systems; GIS; Physical Geography; Digital Elevation Model; DEM; Glaciology; Earth and Environmental Sciences;

    Sammanfattning : Aspects of Error Quantification and Evaluation in Digital Elevation Models for Glacier Surfaces This study explores methods to quantify and evaluate error in digital elevation models (DEMs) built from remotely sensed elevation data of the Hintereisferner glacier. A special focus lies on glacier surfaces because glaciers are often inaccessible for field observations but at the same time prone to measurement errors. LÄS MER

  4. 4. Inductively-Coupled Plasma Etching for Nanoimprint Si-masters

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

    Författare :Oskar Boström; [2019]
    Nyckelord :NIL; Semiconductor; EBL; SEM; ICP-RIE; Fluorine Etching; Physics; Technology and Engineering;

    Sammanfattning : In the last decades, engineers have been pushing semiconductor technology towards fabricating ever smaller devices, and will eventually pass the lower limit of currently commonplace optical lithographic techniques. New techniques have been developed, such as nanoimprint lithography. LÄS MER

  5. 5. Patterning of the neural tube: A 3D computational modelling approach

    Master-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik; Lunds universitet/Beräkningsbiologi och biologisk fysik

    Författare :Ariane Ernst; [2019]
    Nyckelord :gene regulatory networks; neural tube patterning; patterning of the neural tube; dopaminergic neurons; parkinson s disease; computational modelling; stem cell; GRN; Biology and Life Sciences; Physics and Astronomy;

    Sammanfattning : Neurodegenerative diseases such as Parkinson’s can be treated with stem-cell derived specialized neurons. In order to achieve precise directed neural differentiation in vitro we need to understand the gene regulatory mechanisms behind in vivo neural tube patterning. LÄS MER
