  1. 1. Synchrotrons as a Source for Soft X-Ray Lithography

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Thomas Joseph Grandsaert Jr; [2021]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : To move to lower modes in extreme ultra-violet lithography (EUVL) technology (and keep up with Moore’s law), new sources of soft X-ray radiation must be developed. It is clear from previous studies that Free Electron Lasers (FELs) can easily meet the in-band power requirements at these lower wavelength modes, however detailed studies for insertion devices (undulators) as a soft X-ray lithography (SXL) source are due for a re-evaluation.

  3. 2. Fabrication and Optimization of a Nanoplasmonic Chip for Diagnostics

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

    Författare :Jonas Segervald; [2019]
    Nyckelord :AFM; NIL; SPR; SERS; nanohole; nanohole array; nanoimprint lithography; physical vapor deposition; plasma treatment; plasmonic; plasmons; surface plasmon resonance; localized surface plasmon resonance; metal enhanced fluoresence; surface enhanced raman spectroscopy; transmittance; nanoplasmonic; signal enhancement;

    Sammanfattning : To increase the survival rate from infectious- and noncommunicable diseases, reliable diagnostic during the preliminary stages of a disease onset is of vital importance. This is not trivial to achieve, a highly sensitive and selective detection system is needed for measuring the low concentrations of biomarkers available. LÄS MER

  4. 3. 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

  5. 4. Handling of long DNA - applications and polymer physics

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

    Författare :Alexandra Kühnlein; [2016]
    Nyckelord :Biophysics; microfluidics; DLD; DNA; sorting; Physics and Astronomy;

    Sammanfattning : This thesis provides a proof of principle that deterministic lateral displacement (DLD) can be used to spatially separate DNA molecules by size. In order to achieve high separation quality, the pressure range, i.e. flow velocity has to be chosen carefully. LÄS MER

  7. 5. Patterning of Highly Conductive Conjugated Polymers for Actuator Fabrication

    Master-uppsats, Linköpings universitet/Biosensorer och bioelektronik

    Författare :Daniel Falk; [2015]
    Nyckelord :Biosensors; Bioelectronics; Microactuators; Conjugated polymers; Polypyrrole; PEDOT; Soft Lithography; Microcontact printing; Vapor phase polymerization; Drop-on-Demand printing; Photolithography; Lift-off;

    Sammanfattning : Trilayer polypyrrole microactuators that can operate in air have previously been developed. They consist of two outer layers ofthe electroactive polymer polypyrrole (PPy) and one inner layer of a porous poly(vinylidene flouride) (PVDF) membranecontaining a liquid electrolyte. LÄS MER
