Effect of Chemical Treatments on ITO and OLED Device

Abstract:

For an OLED, its electrodes and organic film stack determine its performance. In this paper, we study the effect of acidic (Sulfuric acid) and basic (Sodium Hydroxide) ITO surface treatments. Resistance variation, roughness variation and etc. are recorded. Their effect on device performance is studied by fabricating OLED of m-MTDATA/NPB/Alq3/BCP/LiF/Al structure. The difference in device characteristics with different overlaying Hole Injection Layer (HIL) is studied by comparing fabricated devices
