    Sammanfattning : A new generation of composites, frequently referred to as nanocomposites, are making research and engineering impact worldwide. Particularly, the incorporation of carbon nanotubes (CNT) into polymers is attractive, due to the generally good processability of polymers and the unprecedented properties of nanotubes. LÄS MER

  4. 8. Memory Effects on Iron Oxide Filled Carbon Nanotubes

    Författare :Carlos Cava; Clas Persson; Lucimara Roman; Krister Svensson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Memory devices; Carbon Nanotubes; energy; nanotechnology; Iron Oxide;

    Sammanfattning : In this Licentiate Thesis, the properties and effects of iron and iron oxide filled carbon nanotube (Fe-CNT) memories are investigated using experimental characterization and quantum physical theoretical models. Memory devices based on the simple assembly of Fe-CNTs between two metallic contacts are presented as a possible application involving the resistive switching phenomena of this material. LÄS MER

  5. 9. A Theoretical Study of Carbon Nanotubes in Electronic Packaging Applications

    Författare :Zhili Hu; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; simulation; thermal interface material; continuum; electronic packaging; MDs; CNT;

    Sammanfattning : The continuous decrease in size of transistors has allowed more components to be integrated in a single unit area and brings a range of opportunities as well as problems to the electronic packaging industry. To meet these challenges, the introduction of Carbon Nanotubes (CNT), which display a series of extraordinary properties, have attracted great interest. LÄS MER
