Carrier transport in organic semiconductors exhibits characteristic behavior based on both dynamic and static disorder, especially when the energy disorder is small and the dynamic disorder is not negligible. In the case of high orderability, not only the energy disorder but also the spatial correlation changes with orderliness, and the competition between static and dynamic disorder also changes due to the difference in spatial correlation. Therefore, we performed a Monte Carlo simulation using Ph-BTBT and PNP derivative molecules as test molecules using both Marus and model quantu CT rate model that takes into account the vibrational levels inherent to the molecules with differences of spatial correlation. We have clarified how the temperature and electric field dependence of the mobility changes according to the change in spatial correlation with the change in order.
