We investigated the switching of resistance between two discrete values, known as random telegraph noise (RTN), observed in carbon nanotube peapod transistors [single-walled carbon nanotubes (SWNTs), C60-peapods, and Cs-encapsulated SWNTs (so-called Cs-peapods)]. By analyzing the features of the RTN, we suggest that this noise for SWNTs is due to the random transition of defects between two meta-stable states, activated by inelastic scattering with ballistic electrons. The noise for C60-peapods (Cs-peapods) is attributed to the motion of C60s (Cs) in the nanotubes.
