Scanning tunneling microscopy study of the surface of C60 decagonal crystals grown from n-hexane

A well-developed surface of a decagonal C60 crystal grown from n-hexane has been imaged directly by STM with molecular resolution. Fairly regular patterns have been obtained over large surface areas. However, no internal structure of individual carbon molecules could be observed. This means that some orientational motion persists in the molecular packing of the decagonal crystal as also demonstrated in cubic C60 crystals.
