Gaussian disorder model for charge transport of organic semiconductors, suggests that the field dependence of mobility arises from the energetic disorder, σ. In this study, we demonstrate that spatial correlations in energy levels modify the field dependence of mobility and cause the C-factor, influenced by competition with small polaron conduction, independently of σ. Our findings indicate that spatial correlations affect the temperature dependence of mobility.
