    • Ab-initio electron transport calculations of carbon based string structures 

      Tongay, S.; Senger, R. T.; Dag, S.; Çıracı, Salim (American Physical Society, 2004)
      The new stable structures of carbon-based strings and their unusual electronic transport properties were discussed. Total energy and electronic structure calculations using first principles pseudopotential plane wave method ...

    • Collective modes in a quasi-one-dimensional, two-component electron liquid 

      Tanatar, Bilal (Pergamon Press, 1994)
      Under favorable conditions, a new collective mode besides the usual plasmons may exist in degenerate electron-hole liquids. We calculate the dispersion and damping of this new mode (called the acoustic plasmon mode) in a ...

    • 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. ...

    • 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) ...
