Abstract
Fullerene crystals or films have drawn much interest\nbecause they\nare good candidates for use in the construction of electronic devices.\nThe results of theoretical calculations revealed that the conductivity\nproperties of <i>I<sub>h</sub></i>-C<sub>80</sub> endohedral\nmetallofullerenes (EMFs) vary depending on the encapsulated metal\nspecies. We experimentally investigated the solid-state structures\nand charge-carrier mobilities of <i>I<sub>h</sub></i>-C<sub>80</sub> EMFs La<sub>2</sub>@C<sub>80</sub>, Sc<sub>3</sub>N@C<sub>80</sub>, and Sc<sub>3</sub>C<sub>2</sub>@C<sub>80</sub>. The thin\nfilm of Sc<sub>3</sub>C<sub>2</sub>@C<sub>80</sub> exhibits a high\nelectron mobility μ = 0.13 cm<sup>2</sup> V<sup>–1</sup> s<sup>–1</sup> under normal temperature and atmospheric pressure,\nas determined using flash-photolysis time-resolved microwave conductivity\nmeasurements. This electron mobility is 2 orders of magnitude higher\nthan the mobility of La<sub>2</sub>@C<sub>80</sub> or Sc<sub>3</sub>N@C<sub>80</sub>.
