Microstructural studies of organic light-emitting devices by Monte Carlo simulation of two-dimensional triangles

The fast degradation of organic light-emitting devices (OLEDs) remains as the main obstacle to the commercialization of OLEDs. Among the failure mechanisms proposed, crystallization of the amorphous Alq3 film that leads to the quenching of electroluminescence plays a crucial role and is little understood. Because in situ studies of the Alq3 layer, with the probing of thin organic film by, for example, x-ray diffraction, are very difficult, if …
