  1. 1. Block copolymer-based hybrid nanomaterials for nanoimprint applications

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Lunds Tekniska Högskola

    Författare :Philip Sellin; [2022]
    Nyckelord :Block copolymer; Sequential infiltration synthesis; Nanoimprint lithography; Reactive ion etching; Self-assembly; Thermal annealing; Solvent vapour annealing; Nanoprocessing; Nanofabrication; Antibacterial; Technology and Engineering;

    Sammanfattning : In this Master’s thesis project, a block copolymer (BCP) film was used in combination with sequential infiltration synthesis and etching to manufacture a nanoimprint lithography stamp consisting of silicon. The BCP film was designed to contain perpendicularly aligned hexagonally placed cylinders, a pattern that will later be investigated for antibacterial properties after being transferred via nanoimprint lithography to a polymer film.

  3. 2. Creating nanopatterned polymer films for use in light-emitting electrochemical cells

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Thomas Moberg; [2018]
    Nyckelord :Thermal nanoimprint lithography; soft stamp; intermediate polymer stamp; Light-emitting electrochemical cell; LEC; Super Yellow; polystyrene; poly ethylene oxide ; nanopattern;

    Sammanfattning : Thermal nanoimprint lithography (T-NIL) is a cheap and fast technique to produce nanopatterns in polymeric materials. It creates these patterns by pressing a stamp down into a polymer film that has been heated above its glass transition temperature. LÄS MER

  4. 3. Polymer structures for photovoltaics using colloidal self-assembly, thermal nanoimprinting and electrohydrodynamic annealing

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för fysik

    Författare :Ivan Huuva; [2012]
    Nyckelord :electric field; nanoimprinting; nanoimprint lithography; nil; electrohydrodynamic; ehd; polymer; organic electronics; photovoltaics; solar cells; patterning; self-assembly; colloidal crystal; imprint annealing; embedded annealing; patterning;

    Sammanfattning : The efficiency of an organic photovoltaic cell depends mainly on its morphology where an exciton has to migrate to a p-n junction to create a photocurrent. Therefore the distance from the bulk of the cell to a junction interface should not exceed the diffusion length of the exciton. LÄS MER

  5. 4. Development of a single-step fabrication process for nanoimprint stamps

    Magister-uppsats, Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Författare :Khan Mohammad Moniruzzaman; [2011]
    Nyckelord :;

    Sammanfattning : In this work we have investigated and developed an uncomplicated one step fabrication method to construct Nanoimprint Lithography (NIL) stamps with sub-100nm resolution. The fabrication method includes Electron Beam Lithographical (EBL) patterning using negative tone resist Hydrogen Silsesquioxane (HSQ). LÄS MER
