    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Thin films; magnetron sputter-deposition; in situ and real-time characterization; early film growth stages; residual stress; manipulation of morphology; Couches minces; pulvérisation magnétron; caractérisation in situ en temps réel; premiers stades de croissance; contraintes résiduelles; manipulation de morphologie;

    Sammanfattning : Vapor-based growth of thin metal films with controlled morphology on weakly-interacting substrates (WIS), including oxides and van der Waals materials, is essential for the fabrication of multifunctional metal contacts in a wide array of optoelectronic devices. Achieving this entails a great challenge, since weak film/substrate interactions yield a pronounced and uncontrolled 3D morphology. LÄS MER

  3. 3. High-rate reactive magnetron sputter deposition and characterization of metal oxide films

    Författare :Maryam Kharrazi Olsson; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Sammanfattning : Molybdenum oxide films with good electrochromic properties were produced by single- and dual-target sputtering. Dual-target deposition was shown to be able of yielding optically functional films at much higher rates than that for single-target depositions. LÄS MER

  4. 4. Thin films for indoor air monitoring : Measurements of Volatile Organic Compounds

    Författare :Umut Cindemir; Niklasson Gunnar; Claes-Göran Granqvist; Lars Österlund; Magnus Willander; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; gas sensor; thin film; adcanced gas depostion; sputter deposition; nickel oxide; gold nanoparticles; indium tin oxide; acetaldehyde; formaldehyde;

    Sammanfattning : Volatile organic compounds (VOCs) in the indoor air have adverse effects on the dwellers residing in a building or a vehicle. One of these effects is called sick building syndrome (SBS). LÄS MER

  5. 5. Magnetic Heterostructures : The Effect of Compositional Modulation on Magnetic Properties

    Författare :Inna Soroka; Roger Wäppling; Björgvin Hjörvarsson; Rudolf Schäfer; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Materials science; Magnetism; Sputter deposition; Superlattice; Multilayers; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : The effect of compositional modulation on structural and magnetic properties of magnetic heterostructures was explored. The systems under focus were ferromagnetic superlattices Fe81Ni19/Co, metal-insulator multilayers Al2O3/Ni81Fe19, nanoparticles and artificial multilayered pillars. LÄS MER
