    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mechanical properties; thermophysical properties; stepper motor; ultra-high vacuum; inertial-mass; low temperatures; scanning tunneling microscopy; optical propertie; Fysik; Semiconductory physics; Physics; scanning tunneling luminescence; local probe; photon emission; local carrier injection; Halvledarfysik; Fysicumarkivet A:1998:Lindahl;

    Abstract : This thesis discusses some of the fundamental requirements needed to be fulfilled when constructing a low temperature scanning tunnelling microscope (STM). Three different designs, two non-vacuum and one ultra-high vacuum (UHV), based on either inertial-mass or novel stepper motor principles are presented. READ MORE

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

    Author : Fredrik Olsson; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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.
