Plasma enhanced deposited polyaniline on single and bilayered TiO2 electrodes for the heterojunction structure |
| 초록 |
Aniline monomer was polymerized and deposited by plasma enhanced technique on single and bilayered TiO2 thin films coated on the fluorine doped tin oxide (FTO) glass for the fabrication of p-n heterojunctions. The deposition of the single and double layered TiO2 was achieved through doctor blade and dip coating technique respectively. The fabricated p-n heterojunction structures were morphologically, optically and structurally characterized by field emission scanning electron microcopy (FESEM), Raman and X-rays photon electron spectroscope (XPS) studies. The IV characteristics indicated that a pn heterojunction at nano-crystalline single and bilayered TiO2/polyaniline interface was created which exhibited the typical ohmic behavior. PANI/bilayered heterojunction achieved high current which was attributed to the substantial deposition of PANI into the bilayered thin film and resulted to the enhanced interfacial contact between PANI with TiO2 layers. |
