    • Ab initio study of hydrogenic effective mass impurities in Si nanowires 

      Peelaers, H.; Durgun, E.; Partoens, B.; Bilc, D. I.; Ghosez, P.; Van De Walle C. G.; Peeters, F. M. (Institute of Physics Publishing, 2017-01)
      The effect of B and P dopants on the band structure of Si nanowires is studied using electronic structure calculations based on density functional theory. At low concentrations a dispersionless band is formed, clearly ...
    • Intimate relationship between structural deformation and properties of single-walled carbon nanotubes 

      Yildirim, T.; Gulseren O.; Ciraci, S. (2002)
      Carbon nanotubes continue to surprise scientists with their novel properties. Recently we have discovered many intimate relationships between structural deformation and the properties of single-walled nanotubes (SWNT), ...
    • Lattice dynamics and elastic properties of lanthanum monopnictides 

      Gökoǧlu G.; Erkişi, A. (2008)
      In this study, first principles calculation results of the second order elastic constants and lattice dynamics of two lanthanum monopnictides, LaN and LaBi, which crystallize in rock-salt structure (B1 phase), are presented. ...
    • Magic gold nanotubes 

      Senger, R.T.; Daǧ, S.; Çiraci, S. (2005)
      In recent ultra-high-vacuum transmission-electron-microscopy experiments evidence is found for the formation of suspended gold single-wall nanotubes (SWNTs) composed of five helical strands. Similar to carbon nanotubes, ...
