Morphology of C-60 crystals grown from the vapor phase

The morphology of C-60 crystals grown from the vapor phase have been studie d. In all observations, only hexagonal and rectangular shaped crystal faces were found. Very different morphology, highly faceted {111} faces and flat {100} faces were observed using scanning electron microscopy (SEM) and ato mic force microscopy (AFM). The highly regular shape and similar distance between all neighboring macro steps observed for the {111} faces can be explained by taking into account that edges of two adjacent {111} and {100} planes can act as step sources.
