Abstract
With continuum-based density-functional theory, we have analyzed the liquid -crystal phases of finite-sized capped carbon nanotubes as a function of na notube length and diameter for (i) the case when the nanotubes interact via the fully attractive van der Waals force; and (ii) when such interactions are screened out and the force is hard-core repulsive only. In the case of the former, we find that the columnar phase preempts all other phases at an y reasonable temperature. This result is consistent with the formation of n anotube ropes during the high-temperature growth processes in laser vaporiz ation and carbon are experiments.
