  6. 4. Photoemission from Alkali Metal Overlayers: Quantum Wells, Photoelectron Interference and Atomic Structure Changes

    Author : Dan Claesson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum well states; surface structure; alkali metals; angle resolved photoemission; surface electronic phenomena; thin films; collective excitations; electronic structure;

    Abstract : Angle resolved photoelectron spectroscopy is used to investigate alkali metal overlayers on noble metal surfaces. The work deals with interference in photoemission, bulk electronic structure and adsorption induced changes of atomic structure, respectively. The relative importance of surface and bulk in photoemission has remained largely unexplored. READ MORE

  7. 5. Surface analysis of low dimensional materials : revealing their electronic properties by advanced spectroscopy

    Author : Vladimir Miranda la Hera; Thomas Wågberg; Eduardo Gracia-Espino; Tomas Edvinsson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Low-dimensional materials; surface science; surface-sensitive techniques; angle-resolved photoemission spectroscopy; ultraviolet photoemission spectroscopy; electronic properties;

    Abstract : Low-dimensional materials (0D, 1D, 2D) have been widely used to develop modern miniaturized (micro- and nano-) technology. The use of these materials come from their extraordinary optical, electrical, thermal, and mechanical properties, which are very different from the bulk crystal. READ MORE
