| Research Abstract |
In order to elucidate the scattering behavior of gas molecules on surfaces covered with carbon nanotubes, we performed the molecular beam scattering experiments and Monte Carlo simulations for the free-standing films of carbon nanotubes. The results showed that the efficient energy accommodation originates from the multiple collisions of incident molecules with carbon nanotubes in the topmost layer of the film. In addition, we developed new molecular beam sources to conduct scattering experiments with various gas species and a wide range of incident energy.
