The scattering process of helium molecules on vertically aligned single-walled carbon nanotubes (VA-SWNTs) was investigated using molecular beam technique. The accommodation coefficients for VA-SWNT films on quartz substrates at room temperature are remarkably high compared to those for bare substrates, showing the effectiveness of the surface modification with VA-SWNT films for enhancing the energy transfer between gas molecules and surfaces in rarefied gas flows. The measurement for the free-standing samples, which enabled us to evaluate the scattering process in detail without the presence of substrates, suggested that most molecules have enough number of collisions with SWNTs for efficient energy transfer at the topmost of the films.
