    • Adsorption site of alkali metal overlayers on Si(001) 2 × 1 

      Batra, I. P.; Çıracı, Salim (1992)
      The alkali metal semiconductor interfaces are currently being investigated by a variety of tools. Most studies to date at half a monolayer coverage have shown preference for either a quasi-hexagonal (H) site or a long-bridge ...
    • Fast and accurate analysis of large-scale composite structures with the parallel multilevel fast multipole algorithm 

      Ergül, Ö.; Gürel, L. (Optical Society of America, 2013)
      Accurate electromagnetic modeling of complicated optical structures poses several challenges. Optical metamaterial and plasmonic structures are composed of multiple coexisting dielectric and/or conducting parts. Such ...
    • 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, ...
    • XPS characterization of Au (core)/SiO2 (shell) nanoparticles 

      Tunc, I.; Süzer, Şefik; Correa-Duarte, M. A.; Liz-Marzán, L. M. (American Chemical Society, 2005)
      Core-shell nanoparticles with ca. 15-nm gold core and 6-nm silica shell were prepared and characterized by XPS. The Au/Si atomic ratio determined by XPS is independent of the electron takeoff angle because of the concentric ...
