    • Ab initio temperature dependent studies of the homoepitaxial growth on Si(0 0 1) surface 

      Dağ, S.; Çıracı, Salim; Kılıç, Ç.; Fong, C. Y. (2001)
      We performed ab initio zero temperature and finite temperature molecular dynamics calculations to investigate the homoepitaxial growth on the Si(0 0 1) surface. How do the deposited atoms (adatoms) form addimers and how ...
    • Adsorption of group IV elements on graphene, silicene, germanene and stanene: dumbbell formation 

      Ozcelik, V. O.; Kecik, D.; Durgun, E.; Çıracı, Salim (ACS Publications, 2014-12-09)
      Silicene and germanene derivatives constructed from periodic dumbbell units play a crucial role in multilayers of these honeycomb structures. Using first-principles calculations based on density functional theory, here ...
    • Effects of silicon and germanium adsorbed on graphene 

      Aktürk, E.; Ataca, C.; Çıracı, Salim (A I P Publishing LLC, 2010)
      Based on the first-principles plane wave calculations, we studied the adsorption of Si and Geon graphene. We found that these atoms are bound to graphene at the bridge site with a significant binding energy, while many ...
    • Finite temperature studies of Te adsorption on Si(0 0 1) 

      Sen, P.; Çıracı, Salim; Batra, I. P.; Grein, C. H.; Sivananthan, S. (Elsevier, 2002)
      We perform first principles density functional calculations to investigate the adsorption of Te on the Si(0 0 1) surface from low coverage up to a monolayer coverage. At low coverage, a Te atom is adsorbed on top of the ...
    • Interaction of adatoms and molecules with single-layer arsenene phases 

      Ersan, F.; Aktürk, E.; Çıracı, Salim (American Chemical Society, 2016-06)
      Recent studies have shown that arsenic can form single-layer phases in buckled honeycomb as well as symmetric washboard structures, named as arsenene. These structures are stable even in freestanding form and are nonmagnetic ...
