The interaction between the inner and outer tubes is derived by summing the Lennard-Jones potentials between atoms in the inner and outer tubes. It is proved that the molecular motor in a thermal bath exhibits a directional motion with the temperature variation of the bath. 关键词: Carbon nanotubes;Thermal effects;Atoms;Nanotechnology;Viscous flow;Crystal lattices;Crystal symmetry;Curve fitting;Molecular motors;Thermal baths
