  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. Dead layer determination for the new implantation detector of the LUNDIUM decay station

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Eleftheria Kosta; [2022]
    Keywords : Physics and Astronomy;

    Abstract : The Nuclear Structure Group in Lund, focuses on nuclear spectroscopy of decays of rare isotopes. A new decay station, called LUNDIUM, is currently being built, which will involve silicon and germanium detectors for the study of these nuclei. This thesis focuses on the characterization of one of the new silicon detectors, the implantation one. READ MORE

  4. 3. Development of a Method to Predict the Adhesion of Industrial Paint Coating

    University essay from KTH/Fiber- och polymerteknologi

    Author : Akheen Sadik; [2022]
    Keywords : Contact angle technique; optical tensiometer; paint coating; adhesion promoter; silane; kontaktvinkel; optisk tensiometer; ytbehandling; adhesion; silan;

    Abstract : I samarbete med Sherwin-Williams AB, utvecklades en metod med kontaktvinkelmätning för att teoretiskt uppskatta vätbarhet och vidhäftningsförmåga av industriella färger på stålsubstrat. Optisk tensiometer och Youngs ekvation kombinerat med OWRK beräkningsmodell användes för att bestämma ytenergier. READ MORE

  5. 4. Fluorine-free electrolytes for Li-ion batteries

    University essay from Uppsala universitet/Strukturkemi

    Author : Filippa Wahlfort; [2021]
    Keywords : Li-ion batteries; fluorine-free;

    Abstract : Lithium-ion batteries are of great importance for today's society. The state-of-the-art batteries that are used today use a fluorinated electrolyte that contains the salt LiPF6 and acts as both a safety hazard and an environmental issue due to its ability to form the toxic gas hydrogen fluoride (HF).
