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>.

Mg掺杂的C_2<60>是一种很有前途的有机材料，可用于提高太阳能电池和薄膜晶体管等有机器件的性能。本文研究了掺镁半导体C_2薄膜的结构与导电性的关系<60>。我们发现Mg掺杂的C_2<60>中含有C<60>_2二聚体和聚合体，并且由于存在几种短长度的C_2聚合体而使晶体质量下降<60>。电导率与Mg含量和晶体质量有关。结果表明，高质量的晶体是提高Mg掺杂C_2O_3有机器件性能的必要条件<60>。
