SWCNTs (image) Swiss Federal Laboratories for Materials Science and Technology (EMPA) Share Print E-Mail Caption On a platinum surface, the planar hydrocarbon precursor folds into an end cap, that in turn acts as seed for the growth of a well-defined carbon nanotube. The image below shows scanning tunneling microscopy images of the precursor, the «folded» end cap, and the resulting carbon nanotube, together with the corresponding structural models.
