PHYSICS-BASED COMPACT MODELING OF ORGANIC ELECTRONIC DEVICES

Abstract : Despite impressive progresses in organic electronic devices, a full theoretical understanding of the device operation is still lacking. The thesis is dedicated to establishing applicable theoretical descriptions of organic electronic devices, and in particular physics-based compact models. Prototypical organic diodes and transistors with various architectures are investigated, with a consistent effort to view and present the effect of charge carrier transport and injection on the observable device phenomena. A particular effort is given to integrate these models in circuit simulators, thus connecting the device-level and system-level outlooks. The approaches used comprise equivalent circuit modeling by impedance spectroscopy, analytical development of physics equations, numerical finite-element-based 2-D simulations, and experimental validations. The results provide significant understanding on the effect of traps and injection barriers on the current-voltage characteristics. Original, fully analytical compact models for rectification diodes and organic field-effect transistors are proposed with reliable numerical and experimental proofs.
