| Outline of Final Research Achievements |
Fullerene often encapsulate mono-metal atom and multiple atoms (cluster) in carbon cage. The entrapped atom(s) donate electrons to the fullerene cages which induces the change of their electronic structure. In this report, ultraviolet photoelectron spectroscopy (UPS) analysis combined with theoretical calculation solved one of the main issues for the structure of entrapped cluster and their electronic structure of endohedral fullerenes. High-pressure conductive measuring method and the empirical study was carried, and it was experimentally confirmed that an endohedral fullerene with a semiconductor at ambient pressure changes to metallic conductivity under high-pressure.
