We have produced carbon tubules by quasi-free vapor condensation. This method is different from the previously reported generation method of carbon tubes (I, 2). Atomic resolution images obtained with a scanning tunneling microscope (STM) reveal that the detailed structures of the tube surfaces are networks of perfect honeycombs. In addition, we observe a superpattern on the tubes due to an incorporated inner tube with different helicity. The smallest tube imaged in our experiments has a diameter of —10 A, which is of the size of Cgo- We suggest that the tubule growth starts with the formation of a fullerene hemisphere. [Pg.227]
