Abstract

The synthesis of nanowire p-n heterojunction diodes with tube-shells of multilayer carbon-nanotubes/polymer/semiconductor-particle around metal nanowire, was investigated. Three-layer polyaniline (PAN)/single-walled carbon nanotubes (SWNTox) films were grown on the walls of gold nanowires coated with multilayers of n-type TiO2 nanoparticles and W12O 41 ions to fabricate the p-n heterojunctions. The UV-vis spectra of films grown on a quartz substrate exhibited a regular increase in absorbance with the number of deposition cycles. The results show that metal nanowires coated with 12 nm thick multilayer tube-shells exhibits the characteristics of a built-in p-n junction at the TiO2/PAN interface.
