Abstract

Electrical transport properties of a heterojunction consisting of two multi-wall carbon nanotubes were studied. The current-voltage characteristics of the junction exhibited reproducible rectifying behavior which could be explained well by the Schottky barrier junction model in the intermediate temperature region. The barrier height and the diffusion potential were determined by fitting the current-voltage characteristics to the generalized diode equation. Noticeable deviations from the ideal behavior were observed both in high and low-temperature regions.
