2. 1. Image dipoles and polarons in organic semiconductors

   Author : Yongzhen Chen; Mats Fahlman; Xianjie Liu; Yiqiang Zhan; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic electronics; Interface dipole; Polaron; Conjugated polymer; Photoelectron spectroscopy; N-type doping; Electron transport material;

   Abstract : The rapid development of organic electronics depends on the synthesis of new π-conjugated molecules/polymers and the exploration of fundamental physics. However, most of the efforts have been concentrated on the former, leading to a lack of thorough understanding of many important concepts, which will become the ultimate limiting factor for overall performance and applications.
