Theory of Charge Transport in Molecularly Doped Solids

9614848肯克雷在静电复印和电致发光显示设备方面的不断发展要求对分子掺杂固体中的电荷传输有详细的了解。这笔赠款是新墨西哥大学和密苏里大学罗拉分校两个小组合作的一部分，目的是支持对这一主题的研究。要解决的主要问题是无序和高电场对聚合物薄膜中载流子运动的影响。具体项目除其他外，包括识别载流子、研究场致陷阱、确定光激发后载流子平衡的时间和长度尺度，以及澄清这些现象背后的物理机制所需的其他几个问题。静电印刷和电致发光显示设备使用掺杂的分子固体(例如聚合物薄膜)。涉及光导的基本物理现象，即电荷和光吸收后的电流，包含几个未解答的问题。这笔赠款是为了支持理论工作，以阐明解释这种现象的基本过程，并可能帮助设计出更好的光导体材料。这笔赠款将授予两个团体，一个在新墨西哥大学，另一个在密苏里大学罗拉分校，用于一个合作企业。

9614848 Kenkre Ongoing developments in xerography and in electroluminiscent display devices require a detailed understanding of charge transport in molecularly doped solids. This grant, part of a collaboration between two groups at the University of New Mexico and at the University of Missouri-Rolla is to support research on this subject. The primary issues, to be addressed are the effects of disorder and high electric fields on carrier motion in polymeric films. The specific projects include, inter alia, the identification of the charge carriers, study of the field induced traps, determination of the time and length scales for the equilibration of carriers following photoexcitation and several other issues necessary to clarify the physical mechanism behind the phenomena. %%% Xerography and electroluminescent display devices use doped molecular solids (for example polymer films). The basic physical phenomena involving photoconduction, i. e. charging and currents following absorption of light, contains several unanswered questions. This grant is to support theoretical work to elucidate the fundamental processes which account for the phenomena, and possibly to help design materials which are better photoconductors. The grant is being awarded to two groups, one at the University of New Mexico and another at the University of Missouri- Rolla for a collaborative enterprise.
