Our objective is to understand the conductivity switching processes in polymers, and to apply this phenomenon to the demonstration of reliable, and very high density write once read many times (WORM) memory devices in a hybrid organic/inorganic semiconductor architecture. Recently, and in collaboration with our industrial partners, we have shown that the electrochromic polymer, PEDOT, undergoes an irreversible reduction in conductivity when a large current is passed through it. When placed in series with a nonlinear electrical element (e.g. a Si p-n junction diode), the PEDOT behaves as a fuse in an active matrix array of cross-points, forming a WORM memory; a key component in any electronic technology. Intellectual merit and Broader Impacts: This work will explore both the conductivity mechanisms in electrochromic polymers such as PEDOT, and the nature of organic/inorganic heterojunctions - both fundamental questions explore the nature of organic semiconductor materials. This work can lead to a range of electronic devices employing widely disparate hybrid semiconductor materials systems (i.e. organics with inorganic semiconductors) which can impact the functionalities of both materials systems. The project will engage a diverse pool of students. Coupled to courses already being taught at Princeton by Prof. Forrest in the field of organic thin film devices and materials, and by Prof. Register in polymer chemistry and physics, the team will provide an opportunity for learning in the rapidly expanding field of organic electronics. Our collaboration with our industrial partner, Universal Display Corp., further ensures a rich experience for training students, while providing an immediate technology transfer pathway leading to rapid commercialization.

我们的目标是了解聚合物的导电性切换过程，并将这种现象应用于可靠的，非常高密度的一次写入多次读取（WORM）的存储设备在混合有机/无机半导体架构的演示。 最近，通过与我们的工业合作伙伴的合作，我们已经证明，当大电流通过电致变色聚合物PEDOT时，其电导率会发生不可逆的降低。（例如，Si p-n结二极管），PEDOT表现为交叉点的有源矩阵阵列中的熔丝，形成WORM存储器;任何电子技术的关键部件。 智力价值和更广泛的影响：这项工作将探索电致变色聚合物（如PEDOT）的导电机制，以及有机/无机异质结的性质-这两个基本问题都探索了有机半导体材料的性质。这项工作可以产生一系列采用截然不同的混合半导体材料系统（即有机物与无机半导体）的电子设备，这可能会影响两种材料系统的功能。 该项目将吸引各种各样的学生。 再加上Forrest教授在有机薄膜器件和材料领域以及Register教授在聚合物化学和物理领域已经在普林斯顿教授的课程，该团队将为快速发展的有机电子领域提供学习机会。 我们与我们的工业合作伙伴，通用显示公司，进一步确保了培训学生的丰富经验，同时提供了一个直接的技术转让途径，导致快速商业化。
