  1. 21. STM studies of epitaxial overlayers formed by metal deposition : Mo on MgO, Ni on SiC and Sn on Si

    Författare :Thorbjörn Jemander; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Magnetron sputtering and molecular beam epitaxy (MBE) have been used to deposit metallic overlayers on semiconducting and insulating materials such as Mo on MgO, Ni on SiC(0001) and Sn on Si(111). The layers have been annealed and characterized with scanning tunneling microscopy (STM), Auger electron spectroscopy (AES), low energy electron diffration (LEED), refiecti ve high energy electron diffraction (RHEED) and atomic force microscopy (AFM).

  3. 22. STM studies of overlayers on semiconductor or insulator surfaces

    Författare :Thorbjörn Jemander; Struan Gray; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Scanning tunneling microscopy (STM) operated in ultra-high vacuum (UHV) has been used to study overlayers on semiconductor or insulator surfaces. The overlayers have been deposited by magnetron sputtering, thermal evaporation or by gas exposure, and the investigated material systems include Mo on MgO, Ni on SiC, Sn on Si(lll), C on Si(lO0) and O on Si(lll).

  4. 23. Al-based Thin Film Quasicrystals and Approximants

    Författare :Simon Olsson; Fredrik Eriksson; Lars Hultman; Jensen Jens; Xiaodong Zou; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : In this work, Al-based quasicrystalline and approximant phases have been synthesized in thin films using magnetron sputter deposition. Quasicrystals are structures having long-range order and rotational symmetries which are inconsistent with periodicity. LÄS MER

  5. 24. Soft X-ray Multilayer Mirrors

    Författare :Fredrik Eriksson; David Windt; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis is focused on the design, growth and characterization of soft x-ray multilayer mirrors with the emphasis on the wavelength region called the water window (λ=2.4-4.4 nm). LÄS MER

  7. 25. Physical vapor deposition and thermal stability of hard oxide coatings

    Författare :Ludvig Landälv; Per Eklund; Emmanuelle Göthelid; Björn Alling; Marcus Morstein; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The state-of-the-art tools for machining metals are primarily based on a metal-ceramic composite (WC-Co) coated with different combinations of carbide, nitride, and oxide coatings. Combinations of these coating materials are optimized to withstand specific wear conditions. LÄS MER
