    • High conducting nanowires obtained from uniform titanium covered carbon nanotubes 

      Daǧ, Sefa; Durgun, Engin; Çıracı, Salim (2005)
      We have shown that Ti atoms can form continuous coating of carbon nanotubes at different amount of coverage. The circular cross section changes to a square-like form, and the semiconducting tube becomes ferromagnetic metal ...
    • High-conducting magnetic nanowires obtained from uniform titanium-covered carbon nanotubes 

      Daǧ, Sefa; Durgun, Engin; Çıracı, Salim (American Physical Society, 2004)
      We have shown that a semiconducting single-wall carbon nanotube (SWNT) can be covered uniformly by titanium atoms and form a complex but regular atomic structure. The circular cross section changes to a squarelike form, ...
    • Magic gold nanotubes 

      Senger, R. Tuğrul; Daǧ, Sefa; Çıracı, Salim (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, ...
