    • Disorder-free localization around the conduction band edge of crossing and kinked silicon nanowires 

      Keleş, Ü.; Çakan, A.; Bulutay, C. (A I P Publishing LLC, 2015)
      We explore ballistic regime quantum transport characteristics of oxide-embedded crossing and kinked silicon nanowires (NWs) within a large-scale empirical pseudopotential electronic structure framework, coupled to the ...
    • Finite size effects in cooperative molecular motors 

      Taneri, S.; Yalabik, M. C. (Elsevier B.V., 2003)
      We have studied the ballistic and damped dynamics of finite size cooperative molecular motors. We study the effect of finite size on average quantities such as sliding velocity, as well as the statistics of fluctuations ...
    • High conducting nanowires obtained from uniform titanium covered carbon nanotubes 

      Daǧ, S.; Durgun, E.; Çiraci, S. (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 

      Dag, S.; Durgun, E.; Ciraci, S. (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.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, ...
    • Point normal metal-superconductor (NS) contact in nonballistic regime 

      Askerzade, I. N.; Kulik, I. O. (World Scientific, 2003)
      We analyze the point NS contact conductivity taking into account the depression of superconductivity at high-injection current density and Andreev reflection at the adaptive NS boundary. The dependence of the excess current ...
