Stability of carbon nanoonion C-20@C-60@C-240: Molecular dynamics simulations

Erkoç, Şakir
The structural stability of carbon nanoonion C-20@C-60@C-240 has 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 nanoonion is not so resistive against heat treatment, nor is it as strong as isolated single carbon nanoballs. Although single nanoballs resist heat treatment up to 4300 K, nanoonion disintegrates after 2600 K.
