  2. 2. Towards atomically resolved magnetic measurements in the transmission electron microscope : A study of structure and magnetic moments in thin films

    Författare :Hasan Ali; Klaus Leifer; Peter Van Aken; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Transmission electron microscope; thin films; magnetic moments; electron energy loss spectroscopy; simultaneous acquisition; electron magnetic circular dichroism; Teknisk fysik med inriktning mot materialanalys; Engineering Science with specialization in Materials Analysis;

    Sammanfattning : The magnetic properties of thin metallic films are significantly different from the bulk properties due to the presence of interfaces. The properties shown by such thin films are influenced by the atomic level structure of the films and the interfaces. LÄS MER

  5. 5. First principles simulations of electron transport at the molecule-solid interface

    Författare :Hao Ren; Yi Luo; Nicolás Lorente; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; first principles; electron transport; solid surface; inelastic electron tunneling; Quantum chemistry; Kvantkemi;

    Sammanfattning : In this thesis I concentrate on the description of electron transport properties of microscopic objects, including molecular junctions and nano junctions, in particular, inelastic electron tunneling in surface-adsorbate systems are examined with more contemplations. Boosted by the rapid advance in experimental techniques at the microscopic scale, various electric experiments and measurements sprung up in the last decade. LÄS MER
