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

    Author : Thorbjörn Jemander; Linköpings universitet; []
    Keywords : ;

    Abstract : 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).

  6. 24. STM studies of overlayers on semiconductor or insulator surfaces

    Author : Thorbjörn Jemander; Struan Gray; Linköpings universitet; []
    Keywords : ;

    Abstract : 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).

  7. 25. On the bone response to oxidized titanium implants. The role of microporous structure and chemical composition of the surface oxide in enhanced osseointegration

    Author : Young-Taeg Sul; Göteborgs universitet; []
    Keywords : Oxidized titanium implants; micro arc oxidation; oxide growth; surface oxide properties; bone; biomechanical tests; histomorphometry; enzyme histochemistry.;

    Abstract : Background: Titanium implants have been widely used clinically for various types of bone-anchored reconstructions. A thin native oxide film, naturally formed on titanium implants contacts with bone tissue and has been considered to be of great importance for successful osseointegration. READ MORE
