Abstract: | A numerical model of multilayer organic light-emitting devices is
presented in this article. This model is based on the
drift-diffusion equations which include charge injection, transport,
space charge effects, trapping, heterojunction interface and
recombination process. The device structure in the simulation is
ITO/CuPc (20 nm)/NPD (40 nm)/Alq3 (60 nm)/LiF/Al. There are two
heterojunctions which should be dealt with in the simulation. The
I--V characteristics, carrier distribution and recombination
rate of a device are calculated. The simulation results and measured
data are in good agreement. |
