To explore the universality of the giant Seebeck coefficient (>100 mV K⁻¹) found in our previous study with pure C₆₀ thin films, the thermoelectric properties of high-mobility small-molecule organic semiconductors and their temperature dependencies are investigated. Consequently, various pure organic semiconductors exhibited similar large Seebeck coefficients within the temperature range of 300–360 K. The magnitude of the Seebeck coefficient, its intense temperature dependence, and correlation with the activation energy of electrical conductivity are unique and cannot be elucidated by currently known physical models of thermoelectricity.

有机小分子中巨大塞贝克效应的普遍性†

为了探索我们先前研究中发现的纯C ₆₀薄膜的巨大塞贝克系数（> 100 mV K ^-1）的通用性，研究了高迁移率小分子有机半导体的热电性质及其温度依赖性。因此，各种纯有机半导体在300–360 K的温度范围内均表现出相似的大塞贝克系数。塞贝克系数的大小，其强烈的温度依赖性以及与电导率活化能的相关性是独特的，目前尚无法阐明。已知的热电物理模型。
