Metal to insulator transition at the surface of thin films: an in-situ view
Marco Caputo, Jasmin Jandke, Edoardo Cappelli +12
has long been studied as a prototypical strongly correlated material. The difficulty in obtaining clean, well ordered surfaces, however, hindered the use of surface sensit…
Excitation spectra of transition metal atoms on the Ag (100) surface controlled by Hund's exchange
S. Gardonio, M. Karolak, T. O. Wehling +5
We report photoemission experiments revealing the valence electron spectral function of Mn, Fe, Co and Ni atoms on the Ag(100) surface. The series of spectra shows splittings of hi…
Spectral functions of isolated Ce adatoms on paramagnetic surfaces
S. Gardonio, T. O. Wehling, L. Petaccia +6
We report photoemission experiments revealing the full valence electron spectral function of Ce adatoms on Ag(111), W(110) and Rh(111) surfaces. A transfer of Ce 4f spectral weight…
Determination of the (3x3)-Sn/Ge(111) structure by photoelectron diffraction
L. Petaccia, L. Floreano, M. Benes +6
At a coverage of about 1/3 monolayer, Sn deposited on Ge(111) below 550 forms a metastable (sqrt3 x sqrt3)R30 phase. This phase continuously and reversibly transforms into a (3x3)…
