  We report the spontaneous generation of an Archimedean spiral pattern of
fullerene via the evaporation of solvent. The self-organized spiral pattern
exhibited equi-spacing on the order of micrometer between neighboring stripes.
The characteristics of the spirals, such as the spacing between stripes, the
number of stripes and the band width of stripes, could be controlled by tuning
the thickness of the liquid bridge and the concentration of solution. The
mechanism of pattern formation is interpreted in terms of a specific traveling
wave on the liquid-solid interface accompanied by a stick-slip process of the
contact line.
