  1. 1. Developing an Ar milling process to improve the contact quality to InAs nanowires

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Author : Chris Mkolongo; [2023]
    Keywords : InAs nanowires; Argon milling; Technology and Engineering;

    Abstract : The aim of this work was to develop a stable and reproducible argon milling process for InAs nanowires to remove the native oxide layer that increases electrical resistance. This was done by identifying a few milling parameters and studying them in relation to the milling rate of silicon dioxide (SiO2). READ MORE

  3. 2. μLEDs for optogenetics

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Lukas Wendt; [2018]
    Keywords : μLED; microLED; optogenetics; nitrides; platelets; LNL; epilepsy; Technology and Engineering;

    Abstract : Optogenetics is unfolding new ways for us to study the nervous system and could one day be a standard approach to treat neurological diseases like epilepsy. To selectively study the effects on a subcellular level, microscopic light sources are needed. READ MORE

  4. 3. Block Copolymer Lithographyfor Nano-porous Oxide Thin Films

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Yandi Liu; [2018]
    Keywords : Block Copolymer; Lithography; Nanopatterning; Reactive-Ion Etching; Oxide Thin Films; Blockcopolymer; Litografi; Nanopakning; Reaktion-Jon Etsning; Oxidtunnfilmerna;

    Abstract : This thesis focuses on employing a new patterning technique called block copolymer lithography to transfer the nano-porous pattern from the polymer template to the underlying oxide thin film. Nano-porous block copolymer films are produced by spin-coating polymer solution on wafers followed by annealing, UV exposure and development processes. READ MORE

  5. 4. Electrochemical etching and anodizing as key stages of surface treatment of aluminium foil for electrolytic capacitor industry : Application of Electro Chemical Impedance Spectroscopy as non-destructive characterization of etched anode foil with an anodized dielectric oxide layer

    University essay from Högskolan i Jönköping/JTH, Produktutveckling; Högskolan i Jönköping/JTH, Material och tillverkning

    Author : Harish Appusamy Boopathy; Pavan Kumar Bonthala; [2017]
    Keywords : Surface treatment of aluminum foil for electrolytic capacitor; Anodic oxide forming process; Electro chemical etching; Electrochemical impedance spectroscopy EIS ; Capacitance measurement;

    Abstract : In the initial stage, the sample preparation was done by using the techniques of Anodic etching and anodic forming processes where a repeated trial and error method of sample preparation headed towards making out a suitable sample set for characterization. After this step, the set of 2 different industrial samples were introduced and anodic oxide forming process was carried out in different electrolytes. READ MORE

  6. 5. Ablation of Si with femtosecond laser

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Stefano Prevosti; [2016]
    Keywords : ;

    Abstract : Femtosecond laser ablation of different materials is becoming more and more important in micro- and nanomachining fields. The cutting precision and cost-effectiveness related to this method are turning it into a valid alternative to traditional methods. READ MORE
