Diameter-dependent conductance oscillations in carbon nanotubes upon torsion
K. S. Nagapriya, Savas Berber, Tzahi Cohen-Karni +4
We combine electromechanical measurements with {\em ab initio} density functional calculations to settle the controversy about the origin of torsion-induced conductance oscillation…
Modeling extended contacts to nanotube and graphene devices
Norbert Nemec, David Tomanek, Gianaurelio Cuniberti
Carrier injection into carbon nanotubes and graphene nanoribbons, contacted by a metal coating over an arbitrary length, is studied by various means: Minimal models allow for exact…
Spin currents in rough graphene nanoribbons: Universal fluctuations and spin injection
M. Wimmer, I. Adagideli, S. Berber +2
We investigate spin conductance in zigzag graphene nanoribbons and propose a spin injection mechanism based only on graphitic nanostructures. We find that nanoribbons with atomical…
Magnetism of small transition metal clusters and the effects of isomerisation
Peter Borrmann, Bernd Diekmann, Eberhard R. Hilf +1
We investigate the magnetic properties of small transition metal clusters using a simple statistical model, which requires some input data from ab initio spin-density functional ca…
