项目摘要
Organic thin film semiconductors offer a competitive alternative for the making of electronic devices and circuits. Our key reasons for studying these materials arise from low cost, that some deposition processes are amenable to large area fabrication, and the variability in the physical properties of the deposited films. Currently, light-emitting diode displays using organic thin films are being manufactured and numerous prototype organic thin film transistor circuits have been reported. Unlike the case of single crystal semiconductors, our understanding of the organic thin film semiconductors is limited. Many important issues linked to energy band structures, impurity states, charge excitation and recombination, etc. remain to be resolved. As far as the electronic circuits and devices are concerned, the important parameter affecting performance has been the charge mobility. This parameter generally controls the speed of operation of the device, the gain when the device operates in an amplifier circuit and the charge dynamic during switching. Our proposed research addresses a number of related issues and attempts to examine theoretically (in conjunction with experiments) how charge mobility can increase beyond its current achievable value. Our earlier work suggests that this is very possible. The other significance of this work is to train technologists and engineers in this upcoming field to cope with foreseeable demands particularly in areas such as flexible electronics and sensory circuits. These are areas where the industries in Canada are in a good position to excel given the type of prevailing demands in health care and environmental engineering.
有机薄膜半导体为制造电子器件和电路提供了一种有竞争力的选择。我们研究这些材料的主要原因来自于低成本,一些沉积工艺适合于大面积制造,以及沉积膜的物理性质的可变性。目前,正在制造使用有机薄膜的发光二极管显示器,并且已经报道了许多原型有机薄膜晶体管电路。与单晶半导体的情况不同,我们对有机薄膜半导体的理解是有限的。能带结构、杂质态、电荷激发和复合等许多重要问题还有待解决,电荷迁移率是影响电子电路和器件性能的重要参数。该参数通常控制器件的操作速度、器件在放大器电路中操作时的增益以及切换期间的电荷动态。我们提出的研究解决了一些相关的问题,并试图从理论上(结合实验)研究电荷迁移率如何增加到超出其当前可实现的值。我们早期的工作表明,这是非常可能的。这项工作的另一个重要意义是培养这一即将到来的领域的技术人员和工程师,以科普可预见的需求,特别是在柔性电子和传感电路等领域。这些领域是加拿大的工业在医疗保健和环境工程方面的普遍需求中处于优势地位的领域。
