    • Atomic strings of group IV, III-V, and II-VI elements 

      Tongay, S.; Durgun, Engin; Çıracı, Salim (American Institute of Physics, 2004)
      A systematic first-principles study of atomic strings made by group IV, III-V, and II-VI elements has revealed interesting mechanical, electronic, and transport properties. The double bond structure underlies their unusual ...

    • Characterization of platinum nitride from first-principles calculations 

      Yıldız, A.; Akıncı, Ü.; Gülseren, O.; Sökmen, İ. (Institute of Physics Publishing, 2009)
      We have performed a systematic study of the ground state properties of the zinc-blende, rock-salt, tetragonal, cuprite, fluorite and pyrite phases of platinum nitride by using the plane wave pseudopotential calculations ...

    • Chiral single-wall gold nanotubes 

      Senger, R. T.; Dag, S.; Çıracı, Salim (American Physical Society, 2004)
      The formation of freestanding and tip-suspended chiral-wall (n,m) nanotubes, which were composed of helical atomic strands, from gold atoms was investigated using first-principles calculations, where (n,m) notation defines ...
