    • First-principles study of superlow friction between hydrogenated diamond surfaces 

      Çıracı, Salim; Dağ, Sefa (ASME, 2005)
      Attractive interaction between two clean diamond(001) slabs turns repulsive upon the hydrogenation of surfaces. Even under high loading forces, this repulsive interaction prevents the sliding surfaces from being closer to ...
    • Model study of a surfactant on the GaAs(100) surface 

      Consorte, C. D.; Fong, C. Y.; Watson, M. D.; Yang, L. H.; Çıracı, Salim (Elsevier, 2002-11-01)
      Based on the facts that: (a) the transverse acoustic vibrational branch frequency is softened at the Brillouin zone boundaries of crystalline GaAs; (b) at the surface, the Ga-As bond is stronger than Ga-Te bond; and (c) ...
