ORGANICS/GOALI: Organic/Inorganic Hybrid Semiconductor Memories

我们的目标是了解聚合物中的电导率开关过程，并将这一现象应用于在混合有机/无机半导体架构中可靠的、非常高密度的一次读多次写（WORM）存储器件的演示。最近，通过与我们的工业合作伙伴的合作，我们已经证明，当大电流通过时，电致变色聚合物PEDOT的导电性会发生不可逆的降低。当与非线性电气元件（例如Si p-n结二极管）串联时，PEDOT在交叉点的有源矩阵阵列中充当保险丝，形成WORM存储器；任何电子技术的关键部件。知识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）的电导率机制，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。这项工作可能会导致一系列采用广泛不同的混合半导体材料系统（即有机与无机半导体）的电子设备，这可能会影响两种材料系统的功能。这个项目将吸引各种各样的学生。再加上Forrest教授在普林斯顿大学讲授的有机薄膜器件和材料领域的课程，以及Register教授在聚合物化学和物理领域的课程，该团队将为快速发展的有机电子学领域提供学习机会。我们与工业合作伙伴环球显示公司的合作进一步确保了培养学生的丰富经验，同时提供了直接的技术转移途径，导致快速商业化。

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.
