Title:
A Boltzmann-weighted hopping model of charge transport in organic semicrystalline films
Authors:
Kwiatkowski, Joe J.; Jimison, Leslie H.; Salleo, Alberto; Spakowitz, Andrew J.
Abstract:
We present a model of charge transport in polycrystalline electronic films, which considers details of the microscopic scale while simultaneously allowing realistically sized films to be simulated. We discuss the approximations and assumptions made by the model, and rationalize its application to thin films of directionally crystallized poly(3-hexylthiophene). In conjunction with experimental data, we use the model to characterize the effects of defects in these films. Our findings support the hypothesis that it is the directional crystallization of these films, rather than their defects, which causes anisotropic mobilities. © 2011 American Institute of Physics.
