  • Surface phonons on the NbC(001) and TaC(001) surfaces 
    Bağcı, Sadık; Tütüncü, Hüseyin Murat; Duman, Sıtkı (AMER PHYSICAL SOC, 2012)
    Structural, electronic, and vibrational properties of NbC(001) and TaC(001) are presented, based on the application of plane-wave basis, pseudopotentials, and the generalized gradient approximation of the density functional ...
  • Theoretical examination of whether phonon dispersion in Nb3Sn is anomalous 
    Tütüncü, Hüseyin Murat; Bağcı, Sadık; Duman, Sıtkı (AMER PHYSICAL SOC, 2006)
    Ab initio psuedopotential calculations have been performed for the electronic structure and lattice dynamics of Nb3Sn. It is found that electronic states near the Fermi level show anomalous dispersion. In agreement with ...
  • Theoretical studies of SiC, AlN and their (110) surfaces 
    Bağcı, Sadık; Duman, Sıtkı; Tütüncü, Hüseyin Murat (ELSEVIER SCIENCE SA, 2009)
    We have made theoretical investigations of the structural, elastic and lattice dynamical properties for zinc-blende SiC and AlN. The ground-state properties, i.e., the lattice constants, the bulk modulus, the first-order ...
  • Theoretical study of the structural, electronic and dynamical properties of rocksalt ScN and GaN 
    Duman, Sıtkı; Bağcı, Sadık; Tütüncü, Hüseyin Murat (ELSEVIER SCIENCE SA, 2006)
    Structural, electronic and dynamical properties of the rocksalt structure of the nitride materials ScN and GaN have been studied by employing an ab initio pseudopotential method and a linear response scheme, within the ...
