摘　　要：随着有机电子学的发展,导纳谱方法受到越来越多的关注.本文在导纳谱原理的基础上,总结了目前有机半导体研究中使用的几种导纳谱物理模型,概述了导纳谱在研究载流子迁移率方面的应用,并对导纳谱在定域态分布、负电容现象和其他一些应用研究进行了介绍.With the rapid improvement of organic electronics, the admittance spectra method has become more focused. In this paper, based on the theory of admittance spectra, several admittance spectra physical models for research of organic semiconductors have been summarized. The application of admittance spectra in the research of carrier transference has been reviewed. Additionally, using admittance spectra for research of localized-state distribution, negative capacitance phenomena and other applications have been briefly described.
