 note = {Transport properties of C_60 fullerene peapods and Gd@C_82 metallofullerene peapods are investigated by using the field effect in a gated structure. The results show that C_60 peapods exhibit unipolar p-type characteristics, whereas Gd@C_82 peapods show ambipolar both p- and n-type characteristics. This difference in transport behavior can be explained in terms of a bandgap narrowing of the peapods. One of the important findings is that tunable electronic properties of peapods are achieved by using the different types of encapsulated fullerene molecules.},
