ABSTRACT
Fullerene is a new carbon material system closely related with carbon micro-clusters and/or carbon ultraœne particles. In general, micro-clusters are deœned as atomic clusters consisting of less than 1000 atoms. On the other hand, ultra«ne particles are usually deœned as particles consisting of atoms above the upper limit of micro-clusters. ›e discovery of fullerene was achieved in the process of researching of carbon micro-clusters and/or carbon ultraœne particles. Fullerene is the name of a family of carbon clusters such as C60, C70, and so on. In this chapter, we will use the word “fullerene” mainly as the name of the C60 clusters.
