Comparison of different rate constant expressions for the prediction of charge and energy transport in oligoacenes

Charge and exciton transport in organic semiconductors is crucial for a variety of optoelectronic applications. The prediction of the material-dependent exciton diffusion length and the charge carrier mobility is a prerequisite for tailoring new materials for organic electronics. At room temperature often a hopping process can be assumed. In this work, three hopping models based on Fermi's Golden rule but with different levels of approximationthe spectral overlap approach, the Marcus theory, and the Levich-Jortner theoryare compared for the calculation of charge carrier mobilities and exciton diffusion lengths for oligoacenes, using the master equation approach and Monte Carlo simulations.
