Popis: The transport property of carriers passing through a nanocrystalline Lu3N@C80/Au interface has been studied by measuring impedance under various alternating voltages and DC biases. A depletion layer thicker than 110 µm is recognized in the Lu3N@C80/Au Schottky contact. Such a thick depletion layer indicates that the formation of space charge in the nanocrystalline Lu3N@C80 phase is difficult owing to an increase in LUMO energy, i.e., a decrease in the electron affinity of the Lu3N@C80 molecule. A high interfacial resistance is found to increase the transmission time of the carriers passing through the Lu3N@C80/Au Schottky contact. Such a high interfacial resistance may be ascribed to the low mobility of the carriers in the nanocrystalline Lu3N@C80 phase.
