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
Mugarza, A. ; Mascaraque Susunaga, Arantzazu ; Repain, V. ; Rousset, S. ; Altmann, K. N. ; Himpsel, F. J. ; Koroteev, Y. M. ; Chulkov, E. V. ; Abajo, F. J. García ; Ortega, J. E. | American Physical Society | 2002-12-15Electrons at noble metal surfaces can be confined within terraces leading to one-dimensional surface states. These can be studied with angle-resolved photoemission from vicinal surfaces with regular arrays of (111)-oriented terraces. Here we sho[...]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[...]
