  1. 1. Computational studies of nickel catalysed reactions relevant for hydrocarbon gasification

    Författare :Abas Mohsenzadeh; Högskolan i Borås; []
    Nyckelord :DFT; H2O; CO; adsorption; dissociation; formyl; hydrocarbon combustion; hydrocarbon synthesis; water gas shift; gasification; Ni 111 ; Ni 110 ; Ni 100 ; Resursåtervinning; Resource Recovery;

    Sammanfattning : Sustainable energy sources are of great importance, and will become even more important in the future. Gasification of biomass is an important process for utilization of biomass, as a renewable energy carrier, to produce fuels and chemicals. LÄS MER

  2. 2. Interaction of Ni with SiGe for electrical contacts in CMOS technology

    Författare :Johan Seger; Shi-Li Zhang; Christian Lavoie; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Physics; MOSFET; NiSi; SiGe; phase formation; morphological stability; Fysik; Physics; Fysik;

    Sammanfattning : This thesis investigates the reactive formation of Ni mono-gernanosilicide, NiSi1-uGeu, for contact metallization of future CMOS devices where Si1-xGex can be present in the gate, source and drain of a MOSFET. Although the investigation has been pursued with a strong focus on materials aspects, issues related to process integration in MOSFETs both on conventional bulk Si and ultra-thin body SOI have been taken into consideration.

  3. 3. RhPt and Ni based catalysts for fuel reforming in energy conversion

    Författare :Angélica Viviana González Arcos; Lars J. Pettersson; Klas Engvall; Anker Jensen; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; RhPt bimetallic catalysts; Ni catalysts; ceria-zirconia; potassium tungsten bronze; zirconium dioxide; autothermal reforming; biodiesel; diesel; sulfur; deactivation; tar reforming; steam reforming; biomass gasification; auxiliary power units; naphthalene; Chemical Engineering; Kemiteknik;

    Sammanfattning : Although current trends in global warming are of great concern, energy demand is still increasing, resulting in increasing pollutant emissions. To address this issue, we need reliable renewable energy sources, lowered pollutant emissions, and efficient and profitable processes for energy conversion. LÄS MER

  4. 4. 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).

  5. 5. Source and drain engineering in SiGe-based pMOS transistors

    Författare :Christian Isheden; Mikael Östling; Simon Deleonibus; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; SiGe; source drain; shallow junctions; pMOS; process integration; CVD; epitaxy; etching; Ni silicide; contact resistivity; Elektronik; Electronics; Elektronik;

    Sammanfattning : A new shallow junction formation process, based on selective silicon etching followed by selective growth of in situ B-doped SiGe, is presented. The approach is advantageous compared to conventional ion implantation followed by thermal activation, because perfectly abrupt, low resistivity junctions of arbitrary depth can be obtained. LÄS MER
