Abstract

Two simple empirical models are proposed in order to relate the ITO surface chemical physical properties to the OLED electrical behaviour. Two different organic active layer have been deposited over the ITO substrate: evaporated small organic molecule or spun polymer. In the first case it has emerged that the device current depends on the ITO surface energy through an exponential law, while in the second it is the anode potential barrier that is influenced by the surface energy decreasing. These models allow to tune the device electrical characteristics changing the materials technological features. © 2007 IEEE.
