Abstract

Adsorbed Ne and CH4 on the external surface of a nanotube bundle form quasi-one-dimensional phases at low temperature. This paper presents a study of the phonon spectra and the specific heat associated with these phases. For Ne, two groove phases of different density are investigated, while for CH4 two groove phases of different density and the “three-stripe” phase are studied. In addition, results from classical Monte Carlo simulations are presented which provide information about the thermodynamic behavior of different phases of CH4 at higher temperatures; a dimensionality crossover is indicated by the presence of a distinctive peak in the specific heat.
