The temperature dependence of the anisotropic transient conductivity of a La@C-2v-C-82(Ad) crystal was investigated using flash-photolysis time-resolved microwave conductivity (FP-TRMC) measurements. Results showed that the transient conductivity along the c-axis of the single-crystal increased as the temperature decreased, proving that electron transport can be described by the electronic band-conduction model instead of the electron-hopping model.
