摘要
We report here a shell-by-shell formation of carbon onion by means of in situ high-resolution transmission electron microscopy. An innermost fullerene seed first forms and acts as the central nucleation core to produce a multishell carbon polygon. Then, the carbon polygon can be further transformed to the carbon onions in a controllable manner through the so-called "hot shrinkage" process.
