Mass Transport Induced by Heat Current in Carbon Nanotubes
Figure 2
Temperature gradient dependence of average velocity of He atoms in armchair CNTs for different diameters of the CNTs. The mass densities of He in (5, 5), (7, 7), (10, 10), and (12, 12) are 66.39, 33.89, 16.6, and 16.6 amu/nm3, respectively.
