A Comparative Study of Plasma Enhanced Polymerization of Aniline on Single and Bilayered TiO2 Thin Film Electrode for Heterostructure Diode |
| 초록 |
A heterostructure was fabricated using p-type plasma polymerized polyaniline (PANI) and n-type (single and bilayered) titanium dioxide (TiO2) thin film on FTO glass through plasma enhanced polymerization of aniline. To fabricate p-n heterostructure, a plasma polymerization of aniline was conducted using RF plasma at 13.5 MHz and at the power of 120 W on the single and bilayered TiO2 thin film electrodes. The PANI/bilayered TiO2 heterostructure showed improved current-voltage (I-V) characteristics due to the substantial deposition of PANI molecules into the bilayered TiO2 thin film which might lead the good conducting pathway and reduced the degree of excitons recombination. The change of linear I-V behavior of PANI/TiO2 heterostructure to non linear behavior with top Pt contact layer confirmed the formation of Schottky contact at the interfaces of Pt layer and PANI/TiO2 thin film layers. |
