| 제목 | Lifetime improvement of AZO thin films by electrolysis process and its application OLED |
| 초록 | We had studied the stability of the electrical and optical properties of AZO thin films at Accelerated degradation test. The thin films were prepared by RF magnetron sputtering followed by the box furnace at the air atmosphere. The electrical properties of transparent electrode, showed surface oxidation due to rapid oxygen absorption with increasing annealing temp. The effects of the electrical life time of AZO transparent conductive films were investigated in treated and not treated by electrolysis process. Whereas there were no significant changes in crystallinity of the films, but electrical life time increased from 80 min to 300 min at 350℃ with various electrolysis times. Improved electrical stability are ascribed to desorption of the negatively charged oxygen species from the film surface by the electrolysis process. The change in work-function following the processing time of electrolysis was applied to the fabrication process of device. After checking for light emitting, current density-voltage (J-V) and voltage-brightness (V-L) were measured. The result showed a maximum brightness of 2300cd/m2 at 11V. |
