Hydrogen-induced disintegration of fullerenes and nanotubes: An ab initio study
Savas Berber, David Tomanek
We use ab initio density functional calculations to study hydrogen-induced disintegration of single- and multi-wall carbon fullerenes and nanotubes. Our results indicate that hydro…
Revealing Sub-Surface Vibrational Modes by Atom-Resolved Damping Force Spectroscopy
Makoto Ashino, Roland Wiesendanger, Andrei N. Khlobystov +2
We propose to use the damping signal of an oscillating cantilever in dynamic atomic force microscopy as a noninvasive tool to study the vibrational structure of the substrate. We p…
Direct observation of optically induced transient structures in graphite using ultrafast electron crystallography
Ramani K. Raman, Yoshie Murooka, Chong-Yu Ruan +3
We use ultrafast electron crystallography to study structural changes induced in graphite by a femtosecond laser pulse. At moderate fluences of ~< 21mJ/cm^2, lattice vibrations are…
Transforming carbon nanotubes by silylation: An ab initio study
Kiseok Chang, Savas Berber, David Tomanek
We use ab initio density functional calculations to study the chemical functionalization of single-wall carbon nanotubes and graphene monolayers by silyl (SiH3) radicals and hydrog…
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…
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…
