  1. 1. 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).

  2. 2. Non-equilibrium Surfaces of Metallic Thin Films

    Author : Erik B. Svedberg; Eric E. Fullerton; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Growth and structural characterization of metallic multilayers have been performed on the Mo/W, Mo/V and Ag/Ni systems utilizing magnetron sputtering under ultra-high-vacuum deposition conditions. Structural characterization has been performed both in situ and ex situ with several electron beam probing techniques as well as x-ray diffraction. READ MORE

  3. 3. Microstructural properties of some oxide thin films studied by X-ray diffraction and extended X-ray absorption fine structure

    Author : Arturas Vailionis; KTH; []
    Keywords : ;

    Abstract : The microstructure of some high-temperature superconductorrelated oxide thin films was studied by X-ray Diffraction (XRD)and Extended X-ray Absorption Fine Structure (EXAFS)techniques. A general one-dimensional kinematic x-raydiffraction model was further developed to quantitativelyanalyze the structural properties of complex layered films. READ MORE

  4. 4. 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).

  5. 5. Growth of Ag/Ni Thin Films and Multilayers

    Author : Per Sandström; Jørgen Bøttiger; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY;

    Abstract : Fundamental studies concerning the relation between growth conditions, microstructure and internal stresses of polycrystalline Ag/Ni thin films and multilayers, as well as the relation between growth conditions and the structure of highly oriented Ni films, were performed. All films were depositied using ultra high vacuum based de magnetron sputtering. READ MORE
