Abstract

The structural and thermal properties of Ne and Xe gases adsorbed on the outer surface of a large nanotube bundle have been evaluated using computer simulations. The potential energy model and numerical techniques were previously used to study Ar [N. M. Urban et al., Phys. Rev. B 71, 245410 (2005)]. Heat capacity results for Ne and Xe exhibit peaks associated with reordering and “stripe” melting transitions for these gases.
