近年来，导电聚合物的导电性得到了显著提高。遗憾的是，由于传统的测量方法难以应用于高掺杂无序系统，目前几乎没有关于载流子迁移率和载流子密度测量的报道。在这项研究中，我们开发了一种方法来提取的载流子迁移率在一个高度掺杂的无序系统使用固态光诱导电荷转移反应。结合从光碱产生剂转移到导电聚合物的电荷数，可以从电导率变化中提取载流子迁移率。该方法已成功地应用于不同电导率的导电聚合物。该方法也可用于测量其他无序体系如p型和n型碳纳米管薄膜的载流子迁移率。
Recently, the electrical conductivity of conducting polymers has been significantly improved. Unfortunately, there are nearly no reports on the carrier mobility and carrier density measurements at this stage because traditional measurement approaches are difficult to apply in highly doped disordered systems. In this study, we developed a method to extract the carrier mobility in a highly doped disordered system using a solid state photoinduced charge transfer reaction. Combining the number of the charges transferred from photobase generators to the conducting polymers, the carrier mobility can be extracted from the conductivity change. This approach was successfully applied to conducting polymers with different conductivities. Potentially, this method could also be used to measure the carrier mobility of other disordered systems such as p-type and n-type carbon nanotube films.
