    • Modified genetic algorithms to model cluster structures in medium-size silicon clusters 
      Bazterra, Victor E.; Oña, Ofelia; Caputo, María C.; Ferraro, Marta B.; Fuentealba Rosas, Patricio; Facelli, Julio C. (American Physical Society, 2004)
      Genetic algorithms (GA) were used to investigate the stable isomers of silicon clusters. In order to find the cluster structures, a semiempirical energy function was used by the GA that were further optimized using ...
    • Modified genetic algorithms to model cluster structures in medium-sized silicon clusters: Si18 - Si60 
      Oña, Ofelia; Bazterra, Victor E.; Caputo, María C.; Facelli, Julio C.; Fuentealba Rosas, Patricio; Ferraro, Marta B. (2006)
      This paper presents the results obtained using a genetic algorithm (GA) to search for stable structures of medium-size silicon clusters. This is the third report in which a GA coupled with the MSINDO semiempirical molecular ...
    • Theoretical study of the adsorption of H on Si n clusters, (n=3-10) 
      Tiznado, William; Ona, Ofelia B.; Bazterra, Víctor E.; Caputo, María C.; Facelli, Julio C.; Ferraro, Marta B.; Fuentealba Rosas, Patricio (2005)
      A recently proposed local Fukui function is used to predict the binding site of atomic hydrogen on silicon clusters. To validate the predictions, an extensive search for the more stable Sin H (n=3-10) clusters has been ...
    • Theoretical Study of the Structure and Electronic Properties of Si 3O n -and Si 6O n -(n=1-6) Clusters. ... 
      Tiznado, William; Oña, Ofelia B.; Caputo, María C.; Ferraro, Marta B.; Fuentealba Rosas, Patricio (2009)
      A theoretical study of two series of small clusters, Si 3O n-and Si 6O n -(n=1-6), has been carried out. The minimum energy structures were produced adding an electron to neutral species followed by relaxation at the ...
