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

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
Lobo-Checa, Jorge ; Michel, Enrique G. ; Mascaraque Susunaga, Arantzazu ; Krasovskii, Eugene E. | American Physical Society | 2011-12-13The photoemission cross-section of Shockley states of Cu(111) and Ag(111) surfaces is studied over a wide range of photon energies. The constant initial-state spectra are very different for the two surfaces and show rich structure that does not [...]texto impreso
Mugarza, A. ; Mascaraque Susunaga, Arantzazu ; Perez Dieste, V. ; Repain, V ; Rousse, S. ; Abajo, F. J. García ; Ortega, J. E. | American Physical Society | 2001-09-03STM images show that vicinal Au(788) surfaces are made up or a uniform array of (111)-oriented terraces of similar width (similar to3.8 nm). This uniformity makes it possible to study the electronic Structure of the resulting step superlattice b[...]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

C. | American Physical Society | 2002-09-15Synchrotron-radiation angle-resolved photoemission measurements were performed in the nondoped (PO_2)_4(WO_3)_4(WO_3)_4 compound in order to obtain a detailed picture of the electronic structure. This material is a low-dimensional compound due t[...]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.
