Mobility is an important parameter for evaluating the performance of organic semiconductors. Previously, Wen’s equation was used for theoretical calculations of mobility considering the anisotropy of organic semiconductor crystals based on the hopping model. However, this equation had problems such as overestimating mobility when the continuity of hopping pathways is poor. Therefore, we proposed an analytical formula for calculating the mobility tensor that resolves these problems. In this study, we validated the analytical formula using specific organic semiconductor crystals.
