Theory of Charge Transport in Molecularly Doped Solids

静电复印和电致发光显示器件的不断发展需要对分子掺杂固体中的电荷传输有详细的了解。 这项赠款是新墨西哥州大学和密苏里-罗拉大学两个小组合作的一部分，旨在支持这一主题的研究。 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。 具体项目包括，除其他外，电荷载体的识别，场致陷阱的研究，确定光激发后载流子平衡的时间和长度尺度，以及澄清现象背后的物理机制所需的其他几个问题。 静电复印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）。 介绍了光电导的基本物理现象，即：e.光吸收后的充电和电流，包含几个未回答的问题。 该基金将支持理论工作，以阐明解释这些现象的基本过程，并可能帮助设计更好的光电导体材料。 这笔赠款将授予两个团体，一个在新墨西哥州大学，另一个在密苏里州-罗拉大学的合作企业。

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.
