Mascaraque Susunaga, Arantzazu ; Avila, J. ; Teodorescu, C. ; Asensio, M. C. ; Michel, E. G. | American Physical Society | 1997-03-15The early stages of Fe/Si(111) interface formation have been investigated using x-ray photoelectron diffraction. Deposition of Fe in the range of one monolayer on Si(111)7x7 at room temperature results in the destruction of the 7x7 reconstructio[...]texto impreso
Cortés, R ; Tejeda, A. ; Lobo Checa, J. ; Didiot, C. ; Kierren, B. ; Malterre, D. ; Merino, J. ; Flores, F. ; Michel, E. G. ; Mascaraque Susunaga, Arantzazu | American Physical Society | 2013-09-06We take advantage of complementary high-resolution experimental techniques and theoretical tools to get insight into the alpha-Sn/Ge(111) triangular lattice surface consisting of sp electrons. We report a (3 x 3) phase, characterized by a charge[...]texto impreso
Avila, J. ; Mascaraque Susunaga, Arantzazu ; Michel, E. G. ; Asensio, M. C. ; LeLay, G. ; Ortega Villafuerte, Yanicet ; Perez, R. ; Flores, F. | American Physical Society | 1999-01-11The Sn/Ge(111) interface has been investigated across the 3 x 3 --> , root 3 x root 3 R30 degrees phase transition using core level and valence band photoemission spectroscopies. We find, both above and below the transition, two different compon[...]texto impreso
Ortega, J. V. ; Speller, S. ; Bachmann, A. R. ; Mascaraque Susunaga, Arantzazu ; Michel, E. G. ; Narmann, A. ; Mugarza, A. ; Rubio, A. ; Himpsel, F. J. | American Physical Society | 2000The Cu(111) surface state has been mapped for vicinal surfaces with variable step densities by angle-resolved photoemission. Using tunable synchrotron radiation to vary the Ic dependence perpendicular to the surface, as well as the k(\\) depende[...]texto impreso
Bengio, S. ; Navarro, V. ; González Barrio, Miguel Ángel ; Cortes, R. ; Vobornik, I. ; Michel, E. G. ; Mascaraque Susunaga, Arantzazu | American Physical Society | 2012-07-18The clean surface of Au(100) presents a complex reconstruction characterized by a hexagonal topmost layer. We report an angle-resolved photoemission study of the electronic structure of this surface, including an analysis of the Fermi surface, c[...]texto impreso
Mascaraque Susunaga, Arantzazu ; Avila, J. ; Michel, E. G. ; Asensio, M. C. | American Physical Society | 1998-06-15The electronic structure of Pb/Ge(111) has been probed along the temperature-induced phase transition ct -root 3X root 3R30 degrees double right arrow 3 X 3 using angle-resolved photoemission. The alpha-root 3X root 3R30 degrees phase is metalli[...]texto impreso
Segovia, P. ; Castro, G. R. ; Mascaraque Susunaga, Arantzazu ; Prieto, P. ; Kim, H. J. ; Michel, E. G. | American Physical Society | 1996-11-15The electronic structure and the metallization onset of single-domain K/Si(100)2x1 have been investigated with angle-resolved polarization-sensitive ultraviolet photoemission. The electronic states producing the surface metallization have been s[...]texto impreso
Mugarza, A. ; Ortega, J. E. ; Mascaraque Susunaga, Arantzazu ; Michel, E. G. ; Altmann, K. N. ; Himpsel, F. J. | American Physical Society | 2000-11-15The photoemission cross section of quantum well states in very thin Cu films has been analyzed as a function of photon energy within a wide energy range. We show that this cross section is periodical in k space, peaking around vertical transitio[...]texto impreso
Tejeda, A. ; Cortés, R ; Lobo Checa, J. ; Didiot, C. ; Kierren, B ; Malterre, D. ; Michel, E. G. ; Mascaraque Susunaga, Arantzazu | American Physical Society | 2008-01-18High-resolution photoemission of the Sn 4d core level of Sn/Ge(111)-(3x3) resolves three main components in the line shape, which are assigned to each of the three Sn atoms that form the unit cell. The line shape found is in agreement with an in[...]
