  4. 3. Recombinant production of spider silk for enzymatic phosphorylation

    Master-uppsats, KTH/Proteinvetenskap

    Författare :Kristel Jaiu; [2022]
    Nyckelord :Caddisfly larval silk; FN-4RepCT; phosphorylation; protein kinase A; recombinant spider silk; Nattsländesilke; FN-4RepCT; fosforylering; proteinkinas A; rekombinant spindeltrådsilke;

    Sammanfattning : Ett rekombinant framställt miniatyrspindelsilkeprotein, funktionaliserat med ett Arg-Gly-Asp-motiv som finns i fibronektin, FN-4RepCT, har använts för många olika bioteknologiska tillämpningar, som vävnadsteknik och cellodling, i form av fibrer, filmer och skum. FN-4RepCT kan produceras i Escherichia coli, och det interagerar spontant med sig självt och bildar fibrer under fysiologiska förhållanden. LÄS MER

  5. 4. Study of ohmic contact formation on AlGaN/GaN heterostructures

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Kai-Hsin Wen; [2019]
    Nyckelord :ohmic contacts; wide bandgap; Ta-based; recess etch; N-vacancies;

    Sammanfattning : It is challenging to achieve low-resistive ohmic contacts to III-nitride semiconductors due to their wide bandgap. A common way to reduce the contact resistance is to recess the ohmic area prior to metallization. LÄS MER

  7. 5. Evaluation of graphene as a transparent electrode in GaN-based LEDs by PECVD synthesis of graphene directly on GaN

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Linus Johansson; [2016]
    Nyckelord :PECVD; graphene; transparent electrode; gallium nitride; LED;

    Sammanfattning : A transparent conductive electrode (TCE) is an important component in many of our modern optoelectronic devices like photovoltaics, light emitting diodes and touch screens. These devices require good current injection and spreading as well as a high transparency. LÄS MER
