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中的电导转换过程，并将这一现象应用于在有机/无机混合半导体体系结构中展示可靠的、非常高密度的一次写入多次读取(WORM)存储器件。最近，我们与我们的工业合作伙伴合作，证明了电致变色聚合物PEDOT在大电流通过时，其电导率会发生不可逆转的下降。当与非线性电子元件(例如，硅p-n结二极管)串联放置时，PEDOT在交叉点的有源矩阵阵列中充当保险丝，形成WORM存储器；它是任何电子技术的关键部件。智力优势和更广泛的影响：这项工作将探索PEDOT等电致变色聚合物的导电机制，以及有机/无机异质结的性质--这两个基本问题都探索有机半导体材料的性质。这项工作可以导致一系列电子设备采用完全不同的混合半导体材料系统(即有机和无机半导体)，这可能会影响这两种材料系统的功能。该项目将吸引不同类型的学生。再加上Forrest教授已经在普林斯顿教授教授的有机薄膜设备和材料领域，以及Register教授教授在聚合物化学和物理领域的课程，该团队将提供一个在迅速发展的有机电子领域学习的机会。我们与我们的工业合作伙伴Universal Display Corp.的合作进一步确保了培训学生的丰富经验，同时提供了一条快速商业化的直接技术转移途径。
