The objective of this research is to develop a whole new range of experimental methods that can be used to study the drift velocity (velocity at which charge carriers move in the channel), drift mobility, and trap distribution in polymer/organic transistors. The approach is to study time-resolved transport in transistors such as fast pulse measurements, electrical impulse response measurements, and performing an analysis on half-wave and full-wave rectifier response to deduce the carrier velocities in transistors. Preliminary findings indicate that carriers move at velocities that are comparable to the speed of sound ( ca. 105 cm/s), and that a particular class of circuits called non quasi-static circuits made with polymer transistors can operate at speeds in excess of 20 MHz for 2 micron channel length devices. Such circuits are designed to operate in the regime in which the individual transistors are not fully turned on. It is hoped that by scaling the channel length down to about 100 nm, circuit speeds of several 100 MHz will be possible. The broader impact of this proposal will be to advance the development of integrated organic circuitry and therefore to impact industrial efforts to commercialize organic electronics products. Intellectual Merit: From an educational perspective, the impact will be research-oriented education of both graduate and undergraduate students in Electrical Engineering at UT Austin. This work will also impact the evolution of two specialized courses. This research will also be useful in helping attract more women/minority students into engineering research.

本研究的目的是开发一种全新的实验方法，可用于研究漂移速度（电荷载流子在沟道中移动的速度），漂移迁移率和陷阱分布在聚合物/有机晶体管。 该方法是研究晶体管中的时间分辨输运，如快脉冲测量，电脉冲响应测量，并进行半波和全波整流响应的分析，以推导出晶体管中的载流子速度。 初步研究结果表明，载体以与声速相当的速度移动（约1000米）。105 cm/s），并且对于2微米沟道长度的器件，称为非准静态电路的由聚合物晶体管制成的特定类别的电路可以以超过20 MHz的速度操作。 这样的电路被设计成在单个晶体管不完全导通的状态下工作，希望通过将沟道长度缩小到大约100 nm，电路速度达到几百MHz将是可能的。 这一提议的更广泛影响将是推动集成有机电路的发展，从而影响有机电子产品商业化的工业努力。 智力优势：从教育的角度来看，其影响将是研究生和本科生在UT奥斯汀电气工程的研究型教育。 这项工作还将影响两门专业课程的发展。 这项研究也将有助于吸引更多的妇女/少数民族学生进入工程研究。
