spelling Robust Spin Polarization and Spin Textures on Stepped Au(111) SurfacesLobo-Checa, JorgeMeier, FabianDil, J. HugoOsterwalder, Jürg4 páginas, 3 figuras, 1 tabla.-- PACS numbers: 79.60.Bm, 72.25.-b, 73.20.At.-- et al.-- Trabajo presentado como comunicación oral al "10th International Conference on Atomically Controlled Surfaces, Interfaces and Nanostructures (ACSIN 10)" celebrado en Granada (España) del 21 al 25 de septiembre de 2009.The influence of structural defects, in the form of step lattices, on the spin polarization of the spin-orbit split Shockley surface state of Au(111) has been investigated. Spin- and angle-resolved photoemission data from three vicinal surfaces with different step densities are presented. The spin splitting is preserved in all three cases, and there is no reduction of the spin polarization of individual subbands, including the umklapp bands induced by the step lattice. On the sample with the highest step density studied, where the wave functions are delocalized over several terraces, the spin splitting is enhanced substantially, likely as an effect of the effective surface corrugation as on related surface alloys. The spin texture shows in all cases spin polarization vectors tangential to the Fermi circles, with the same helicities as on Au(111).This work has been supported by the Swiss National Science Foundation and by the Spanish Ramón y Cajal Program.Peer reviewedAmerican Physical SocietySwiss National Science FoundationEuropean CommissionConsejo Superior de Investigaciones Científicas (España)201120112010info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501http://hdl.handle.net/10261/39174reponame:DIGITAL.CSIC.
