    • Energy dependence of the ripple wavelength for ion-beam sputtering of silicon: experiments and theory 

      Castro Ponce, Mario; Gago Fernández, Raúl; Vázquez Burgos, Luís; Muñoz García, J.; Cuerno Rejado, Rodolfo (19/04/2013)
      In spite of the efforts devoted for the last 20 years to elucidating ion-beam sputtering (IBS) as an instance of surface self-organization, the classic view on the main mechanism inducing the morphological instability has ...

      Castro Ponce, Mario; Gago Fernández, Raúl; Vázquez Burgos, Luís Fernando; Muñoz García, J.; Cuerno Rejado, Rodolfo (University of North Texas (UNT) and Sandia National Laboratories (SNL). (Fort Worth, Estados Unidos de América), 05/08/2012)
      In spite of the efforts devoted for the last 20 years to elucidating ion-beam sputtering (IBS) as an instance of surface self-organization, the classic view on the main mechanism inducing the morphological instability has ...

    • Independence of interrupted coarsening on initial system order: ion-beam nanopatterning of amorphous versus crystalline silicon targets 

      Muñoz García, J.; Gago Fernández, Raúl; Cuerno Rejado, Rodolfo; Sánchez García, José Ángel; Redondo Cubero, Andrés; Castro Ponce, Mario; Vázquez Burgos, Luís Fernando (2012-09-19)
      Interrupted coarsening (IC) has recently been identified as an important feature for the dynamics of the typical length-scale in pattern-forming systems on surfaces. In practice, it can be beneficial to improve pattern ...

    • Interplay between morphology and surface transport in nanopatterns produced by ion-beam sputtering 

      Cuerno Rejado, Rodolfo; Muñoz García, J.; Castro Ponce, Mario; Gago Fernández, Raúl; Vázquez Burgos, Luís Fernando (2007-12-01)
      A "hydrodynamic" model has been proposed to describe nanopattern formation and dynamics on amorphous surfaces eroded by ion-beam sputtering (IBS), that relates to descriptions of pattern formation in macroscopic systems ...

    • Nanoscale pattern formation at surfaces under ion-beam sputtering: a perspective from continuum models 

      Cuerno Rejado, Rodolfo; Castro Ponce, Mario; Muñoz García, J.; Gago Fernández, Raúl; Vázquez Burgos, Luís Fernando (01/05/2011)
      Although reports on surface nanostructuring of solid targets by low to medium energy ion irradiation date back to the 1960s, only with the advent of high resolution tools for surface/interface characterization has the high ...

    • Nonuniversality due to inhomogeneous stress in semiconductor surface nanopatterning by low-energy ion-beam irradiation 

      Moreno Barrado, Ana; Castro Ponce, Mario; Gago Fernández, Raúl; Vázquez Martínez, Luís; Muñoz García, J.; Redondo Cubero, Andrés; Galiana Blanco, Beatriz; Ballesteros Pérez, Carmen Inés; Cuerno Rejado, Rodolfo (2015-04-15)
      A lack of universality with respect to ion species has been recently established in nanostructuring of semiconductor surfaces by low-energy ion-beam bombardment. This variability affects basic properties of the pattern ...

      Gago Fernández, Raúl; Vázquez Burgos, Luís Fernando; Plantevin, O.; Metzger, T.H.; Muñoz García, J.; Cuerno Rejado, Rodolfo; Castro Ponce, Mario (2008-06-09)
      The temporal evolution of the characteristic wavelength (lambda) and ordering range (xi) of self-organized nanodot patterns induced during Ar%2B ion beam sputtering on Si(001) and Si(111) surfaces is studied by atomic force ...
