  2. 1. Nanomechanics – Quantum Size Effects, Contacts, and Triboelectricity

    Author : Martin Olsen; Jonas Örtegren; Håkan Olin; Per Gradin; Peter Glans; Rusen Yang; Mittuniversitetet; []
    Keywords : triboelectricity; adatom; ion; charge; mound; quantum size effect; triboelctric nanogenerator; TENG; wind driven; contact; nanomechanics; fri electron model; nanowire cantilever;

    Abstract : Nanomechanics is different from the mechanics that we experience in everyday life. At the nano-scale, typically defined as 1 to 100 nanometers, some phenomena are of crucial importance, while the same phenomena can be completely neglected on a larger scale. 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.
