有机-金属和有机-有机界面在有机薄膜器件中的电荷注入和传输中起着至关重要的作用。如果有机器件的工程和控制要达到无机半导体器件所达到的水平，就必须充分表征和理解它们的电子结构、化学性质和电学行为。最近的基础，以及设备，工作已经表明，电掺杂提供了一个非常有趣的方式来提高载流子注入到分子膜，并最终控制分子水平的排列在其界面。这篇简短的综述强调了目前对掺杂对有机界面影响的认识。
Organic–metal and organic–organic interfaces play crucial roles in charge injection in, and transport through, organic thin film devices. Their electronic structure, chemical properties and electrical behaviour must be fully characterized and understood if engineering and control of organic devices are to reach the levels attained for inorganic semiconductor devices. Recent fundamental, as well as device, work has demonstrated that electrical doping provides a very interesting way to improve carrier injection into molecular films and, eventually, control molecular level alignment at their interfaces. This brief review emphasizes the current understanding of the effects of doping on organic interfaces.
