The modification is found to be sensitive to the ion dose. The cluster ion irradiation with the doses lower than 25×1014 ions/cm2 leads to formation of the pyramid-like nanodots on the film surface. In parallel, Raman spectra show the C60 quality improvement in solid state suggesting film purification from the small CxHy radicals. The irradiation with the doses higher than 25×1014 ions/cm2 activates evident carbon sputtering. The high-dose irradiation also drastically changes the surface nano-pattern yielding the aligned elongated nano-objects. Raman and AFM analysis identifies the nano-objects as the C60 polymeric chains. Formation of the C60 polymeric chains is referred to the effect of shockwaves generated by the C60+ cluster impacts.
