  1. 1. An MST approach to skin perforation using wet etched silicon microneedles

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Gustav Carlsson; [2020]
    Nyckelord :microneedles; laser ablation;

    Sammanfattning : The human skin functions as a strong barrier and when administering medical drugs through the skin a very high concentration of medicine is needed. With the use of microneedles the diffusivity can be increased. LÄS MER

  3. 2. Design and construction of a photoplotter : Building a device for rapid prototyping of PCBs

    Kandidat-uppsats, Uppsala universitet/Fasta tillståndets fysik

    Författare :Gabriel Hajjar; [2018]
    Nyckelord :photoplotter; PCB; printed circuit board; prototyping; mönsterkort; kretskort;

    Sammanfattning : The goal was to build a machine that could rapidly prototype PCBs using a moving light source and photoresist. The project failed, as the UV light did not make it through the lenses used to concentrate it. Better lenses and a laser would allow it to function better. . LÄS MER

  4. 3. Device development for doping evaluation in nanowires using capacitance-voltage measurements

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

    Författare :Emil Nylander; [2016]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This thesis aims to show the prospect of capacitance measurements over nanowire arrays as an evaluation method of the p-doping level in weakly p-doped p-n nanowires. The premise of the method is that there will be a high yield of statistical data regarding the doping level of the nanowires. LÄS MER

  5. 4. Rip off and characterization of nanowire ensembles for photovoltaic applications

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

    Författare :Seyed Alireza Abrand Abadizadeh; [2014]
    Nyckelord :nanowire; solar cell; PDMS; flexible film; Physics and Astronomy;

    Sammanfattning : The main aim of this project was to peel off the epitaxially grown nanowires (NWs) from their native substrate and transfer them to the cheaper carrier substrate in order to make solar cell device from transferred NWs. Potentially the peeling and transferring idea is about to decrease the cost of NWs growth by reusing the native substrate especially for expensive material such as InP and GaAs which are suitable materials for single junction solar cell.

  7. 5. Advanced processing of vertically aligned nanodevices

    Master-uppsats, Lunds universitet/Fysiska institutionen

    Författare :Shantonu Biswas; [2013]
    Nyckelord :photoresist; S1800; photodetector; nanowire; metal contact; Technology and Engineering;

    Sammanfattning : Lithography technique is highly dependent on the photoresist that is used for the processing of the nanodevices. S1800 series photoresist is probably the most used positive photoresist for UV-lithography process. LÄS MER
