title: Nanodiode based on a multiwall CN(x)/carbon nanotube intramolecular junction.
abstract: We prepared multiwall carbon nanotubes (MWCNTs) from the pyrolysis of ferrocene, and CN(x) nanotubes from a mixture of ferrocene and melamine. Under well chosen synthesis conditions, massive multiwall CN(x)/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 CN(x)/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 CN(x)/CNT junctions to their two different atomic and electronic sections.
