    • Chiral single-wall gold nanotubes 

      Senger, R. T.; Dag, S.; Ciraci, S. (American Physical Society, 2004)
      The formation of freestanding and tip-suspended chiral-wall (n,m) nanotubes, which were composed of helical atomic strands, from gold atoms was investigated using first-principles calculations, where (n,m) notation defines ...
    • Nanostructured materials and devices for sensing and energy harvesting applications 

      Kanık, Mehmet (Bilkent University, 2015-08)
      A closer look into the fundamental challenges of the modern world reveals that the increasing demand for energy threatens the evolution of science and technology. Energy-efficiency is thus a fundamental issue in engineering ...
    • Spin filtering in a quantum ring with Rashba coupling 

      Tanatar, Bilal; Moldoveanu V. (IEEE, 2010)
      We study the effect of Rashba spin-orbit coupling on the spin interference in a non-interacting one-dimensional ring connected to two lead theoretically within the non-equilibrium Greens' function formalism. We compute the ...
