Abstract

Abstract We present transport properties of various fullerene nanopeapods used as channels of field effect transistors (FET). C 60 and C 78 fullerenes and [email protected] 82 and [email protected] 82 metallofullerenes peapods FET show both p- and n-type ambipolar behavior. In case of C 90-peapods, all devices have shown so far metallic properties. These novel electronic properties of the peapods can be explained by the so-called band-gap modulation originated from the encaging fullerenes and metallofullerenes in nanotubes.
