  1. 16. The absorption of laser light by rough metal surfaces

    Författare :David Bergström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Produktionsutveckling; Manufacturing Systems Engineering;

    Sammanfattning : In Laser Material Processing of metals, an understanding of the fundamental absorption mechanisms plays a vital role in determining the optimum processing parameters and conditions. The absorptance, which is the fraction of the incident laser light which is absorbed, depends on a number of different parameters. LÄS MER

  3. 17. Adsorption of Organic Phosphines and Thiols on Metal Surfaces

    Författare :Hans Kariis; Per Persson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this thesis investigations of the adsorption of small molecules on metal surfaces are presented. Several surface sensitive analytical methods are used in the studies.Surface modification of gold is a field in which an enormous amount of work has been published in recent years. LÄS MER

  7. 20. Electronic states of adsorbates and insulating overlayers on metal surfaces

    Författare :Fredrik Olsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Shockley surface states; local density of states; scanning tunneling microscope; chemisorption; sodium chloride; noble metals; image states; electronic states; density functional theory;

    Sammanfattning : Electronic states of adsorbates and insulating overlayers provide a wealth of scientifically interesting phenomena with great technological importance. Interesting phenomena arise, for example, from the interaction of electronic states of an adsorbate with the continuum of metal electron states, both propagating bulk states and surface states.
