Simultaneous Extraction of Density of States Width, Carrier Mobility and Injection Barriers in Organic Semiconductors.

ABSTRACT: The predictive accuracy of state-of-the-art continuum models for charge transport in organic semiconductors is highly dependent on the accurate tuning of a set of parameters whose values cannot be effectively estimated either by direct measurements or by first principles. Fitting the complete set of model parameters at once to experimental data requires to set up extremely complex multi-objective optimization problems whose solution is, on the one hand, overwhelmingly computationally expensive and, on the other, it provides no guarantee of the physical soundness of the value obtained for each individual parameter. In the present study we present a step-by-step procedure that enables to determine the most relevant model parameters, namely the density of states width, the carrier mobility an
