“…14, with an image-charge-induced lowering of the injection barrier included in a similar way as in the work of Emtage and O'Dwyer. 20 For thin devices and high disorder strengths the current obtained from the 3D calculations was found to be somewhat higher than that obtained from the 1D drift-diffusion model. It is in this regime that the current density becomes extremely nonuniform.…”

The results of a combined experimental and modeling study of charge transport, recombination and light emission in blue organic light-emitting diodes (OLEDs) based on a polyfluorene derivative are presented. It is shown that the measured temperature-dependent current-voltage curves and the voltage-dependent current efficiency are accurately described using an OLED device model that is based on the separately determined unipolar electron and hole mobility functions. The recombination rate is calculated using the Langevin formula, including recombination of holes with free as well as trapped electrons. The light emission is obtained from the exciton formation profile using independently determined values of the exciton radiative decay probability, the average dipole orientation, and assuming a fraction of singlet excitons ηS =(22±3)%, close to the quantum-statistical value. No additional free parameter is used. This shows that predictive one-dimensional device modeling of OLEDs is feasible.

“…When the bias voltage overcomes the Schottky barrier between the tip and the ferroelectric thin film, charges with the same polarity to the depolarization charges can be injected from the EFM tip to surface. [16][17][18] These charges injected from the EFM tip ͑surface charges͒ are shown in Fig. 3͑a͒.…”
