The minimum energy structures of titanium covered finite-length C(8,0) singlewall carbon nanotubes (SWNT) have been investigated. We first parameterized an empirical potential energy function (PEF) for the CTi system. The PEF used in the calculations includes two- and three-body atomic interactions. Then, performing molecular dynamics simulations, we obtained the minimum-energy configurations for titanium covered SWNTs. The reported configurations include low and high coverage of Ti on SWNTs. We saw that one layer of Ti did not distort the nanotube significantly, whereas two-layer coverage showed an interesting feature: the second layer of Ti pushed the first layer inside the wall, but the general shape of the nanotube was not affected so much.

Titanium coverage on a single-wall carbon nanotube: molecular dynamics simulations Oymak, H; Erkoc, F (Elsevier BV, 2004-05-10) The minimum energy structures of Ti covered (8,0) single-wall carbon nanotube (SWNT) have been investigated theoretically. Using available experimental data and the results of density functional theory calculations, we first parametrized a reliable empirical many-body potential energy function (PEF) for the CTi binary system. The PEF used in the calculations includes two- and three-body atomic interactions. Then performing molecular dynamics simulations at 1 and 300 K, we obtained the minimum-energy configu...
Structural Vibration Analysis of Single Walled Carbon Nanotubes with Atom Vacancies Dogan, Ibrahim Onur; Yazıcıoğlu, Yiğit (2014-11-01) Recent investigations in nanotechnology show that carbon nanotubes have significant mechanical, electrical and optical properties. Interactions between those are also promising in both research and industrial fields. Those unique characteristics are mainly due to the atomistic structure of carbon nanotubes. In this paper, the structural effects of vacant atoms on single walled carbon nanotubes are investigated using matrix stiffness method. In order to use this technique, a linkage between structural mechan...
From carbon nanotubes to carbon nanorods Erkoç, Şakir (2000-09-01) The structural properties of single and multi-wall carbon nanotubes and the formation of carbon nanorods from multi-wall carbon nanotubes have been investigated by performing molecular-dynamics computer simulations. Calculations have been realized by using an empirical many-body potential energy function for carbon. It has been found that carbon nanorod formation takes place with smallest possible multi-wall nanotubes under heat treatment. On the other hand, it has been also found that single-wall carbon na...
Molecular-dynamics simulations of silicene nanoribbons under strain Ince, Alper; Erkoç, Şakir (2012-01-01) Structural properties of silicene nanoribbons (SiNRs) of varying width have been investigated under 5% and 10% uniaxial strain via classical Molecular-Dynamics simulations at 1 and 300?K temperatures by the aid of atomistic many-body potential energy functions (PEFs). It has been found that under strain, SiNRs show such material properties: they are very ductile, with considerable toughness and a very long plastic range before fragmentation.
Effect of chirality on the stability of carbon nanotubes : Molecular-dynamics simulations Erkoc, S; Malcıoğlu, Osman Barış (2001-07-01) The effect of chirality on the structural stability of single-wall carbon nanotubes have been investigated by performing molecular-dynamics computer simulations. Calculations have been realized by using an empirical many-body potential energy function for carbon. It has been found that carbon nanotube in chiral structure is more stable under heat treatment relative to zigzag and armchair models. The diameter of the tubes is slightly enlarged under heat treatment.
