| Research Abstract |
Mg-doped C_<60> is promising material for improving performance of organic devices, such as solar cells and thin film transistors. In this study, we investigated the relationship between structure and electric conduction of semiconducting Mg-doped C_<60> film. We found that Mg-doped C_<60> contains C_<60>-dimers and polymers, and the crystal quality is degraded by the existence of several types of short length C_<60> polymers. Electrical conductivity is related both of Mg concentration and crystal quality. The results indicate that high crystal quality is necessary to improve organic device performance by using Mg-doped C_<60>.
