We prepared multiwall carbon nanotubes (MWCNTs) from the pyrolysis of ferrocene, and CNxnanotubes from a mixture of ferrocene and melamine. Under well chosen synthesis conditions, massive multiwall CNx/carbon nanotube intramolecular junctions were successfully fabricated. The individual nanotubes were used as conductance channels to obtain their transport characteristic information. Measurement results showed that the current-voltage (I-V) curve of the CNx/CNT junction is highly asymmetric, behaving like a diode. Moreover, the devices are very stable in ambient environment. We attribute this nonlinear property of the CNx/CNT junctions to their two different atomic and electronic sections.
