  1. 21. Corrosion Resistant Multi-Component Coatings for Hydrogen Fuel Cells

    Master-uppsats, Linköpings universitet/Tunnfilmsfysik

    Författare :Jakob Steneteg; [2021]
    Nyckelord :Coatings; Hydrogen Fuel Cells; Multi-Component; High Entropy Alloys; Corrosion Resistance;

    Sammanfattning : Multi-component coatings and high entropy alloys have in recent years attracted great interest for research, since they have shown to exhibit properties greater than the com- ponents of their parts. Today’s climate challenges requires transitioning from fossil fuels to renewable energy sources which demands use of new technology and new innovations. LÄS MER

  3. 22. Modeling of carbon plasma discharges in high-power impulse magnetron sputtering

    Master-uppsats, Linköpings universitet/Plasma och ytbeläggningsfysik

    Författare :Henrik Eliasson; [2021]
    Nyckelord :;

    Sammanfattning : Diamond like carbon (DLC) is a metastable state of amorphous carbon that has very important and wide-ranging thin film applications. DLC has a strong resemblance to pure diamond and exhibits many traits of real diamond, like mechanical hardness and chemical inertness, but with a drastically lower deposition cost. LÄS MER

  4. 23. Electric Transport of Rare-earth Metal Oxy-hydride Thin Films

    L3-uppsats, Uppsala universitet/Materialfysik; Uppsala universitet/Tillämpad kärnfysik

    Författare :Suraya Kazi; [2021]
    Nyckelord :Photochromism; Photoconductivity; Rare-earth Metal Oxy-hydride; Electric Transport; Photodarkening; Yttrium Oxy-hydride;

    Sammanfattning : In this project, I investigate the photoconductivenature of photochromic rare-earth metal oxy hydrides (REMHO). Such materials have received increasingscientific attention since they show a color-neutralphotochromic effect that can be applied, e.g., in smartwindows or chromogenic devices. LÄS MER

  5. 24. Study of HfN as seed layer for next generation of BAW RF filters : synthesis, characterization, and investigation of piezoelectric performance

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Eduard Llorens Balada; [2020]
    Nyckelord :HfN; AlScN; AlN; sputtering; XRD; SEM; seed layer; epitaxial growth;

    Sammanfattning : Micro-electro-mechanical systems (MEMS) have become an essential component of a wide range ofelectronic devices over the last decades such as accelerometers, microphones, gas sensors, and filters.During this new millennium, a new radio frequency (RF) technology has been developed to satisfy thetough demands that arose due to the implementation of 5G wireless communication: bulk acoustic wave(BAW) filters.

  7. 25. Magnetron sputtering of highly transparent p-conductive NiO thin films

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Solcellsteknik

    Författare :Martin Book; [2020]
    Nyckelord :Nickel oxide; Magnetron sputtering; Electrochromic; Transmittance; Absorption; Resistivity;

    Sammanfattning : P-type transparent conductors are needed for a wide range of applicationssuch as solar cells and electrochromic smart windows. Solar power is animportant form of energy in today’s society as the threat of global warmingpushes the world towards fossil free energy. LÄS MER
