Abstract For the first time, an effort has been made to evaluate the charge transport properties of semiconducting natural rubber. Four different ratios of iodine-rubber composites are synthesised and tested for charge transport by current density- voltage characteristics (J-V) and impedance spectroscopy. The optimal doping ratio for best mobility value is identified, and the effect of injection barrier height on mobility is discussed. An attempt has also been made to correlate the density of states (DOS) with mobility and doping ratio. The transport properties of semiconducting natural rubber are compared with one of the most popular p-type material, Poly(3-hexylthiophene-2,5-diyl) (P3HT) under the same ambience and experimental conditions to demonstrate its potential as a cost-effective and green alternative organic semiconductor.

半导体天然橡胶（Cis 1,4-聚异戊二烯）的电荷传输特性

摘要 首次尝试评估半导体天然橡胶的电荷传输性能。合成了四种不同比例的碘-橡胶复合材料，并通过电流密度-电压特性 (JV) 和阻抗谱测试电荷传输。确定了最佳迁移率值的最佳掺杂比，并讨论了注入势垒高度对迁移率的影响。还尝试将态密度 (DOS) 与迁移率和掺杂比相关联。在相同的环境和实验条件下，将半导体天然橡胶的传输特性与最流行的 p 型材料之一聚（3-己基噻吩-2,5-二基）（P3HT）进行比较，以证明其作为成本低的潜力。有效和绿色的替代有机半导体。
