Planning Visit: Thin Film/Cellulose Integrated Circuitry International Collaboration between University of Texas at Dallas and the New University of Lisbon

该项目将支持在得克萨斯大学达拉斯分校(UTD)和葡萄牙里斯本新大学(UNL)之间建立一个新的国际研究合作。UNL的研究人员专注于材料研究，最近展示了纤维素纸作为电子设备(如有机薄膜晶体管、逻辑电路和电致变色显示器)物理支撑的基板或作为中间层的使用。将设备构建在纤维素纸的两侧的结构。德州大学达拉斯分校的团队专注于器件设计和工艺集成，最近展示了用于电泳显示器的灵活的CMOS数字门和集成列驱动器、基于有机铁电聚合物P(VDF-TrFE)的非易失性存储器以及基于有机薄膜晶体管和有机发光二极管的柔性显示器。在目前的催化项目中，两个团队将合作开发基于在纤维素衬底上集成新型器件结构和电路的新器件，为非常廉价、高功能的电子纸提供可能性。通过该奖项支持的规划访问的更广泛影响是巨大的。以纤维素为基础的新电子领域的发展具有潜在的变革性，互补的研究专业知识和基础设施将促进强有力的国际合作。学生研究人员将参加计划中的葡萄牙之行，并获得宝贵的国际经验和网络。预计的后续活动还包括为美国和葡萄牙学生制定长期交换计划。

This project will support the establishment of a new international research collaboration between the University of Texas-Dallas (UTD) and the New University of Lisbon (UNL) in Portugal. Researchers at UNL focus on materials research, and recently demonstrated the use of cellulose based paper as either a substrate for physical support of electronic devices (such as organic thin film transistors, logic circuits and electrochromic displays) or as an ?interstrate? structure where the device is built on both sides of the cellulose sheet. The group at UT Dallas focuses on device design and process integration, and recently demonstrated Flexible CMOS digital gates and integrated column drivers for electrophoretic displays, non-volatile memory based on the organic ferroelectric polymer P(VDF-TrFE), and flexible displays based on organic thin-film transistors and organic light emitting diodes. In the current catalytic project, the two teams will work together to develop new devices based on integrating novel device structures and circuits on cellulose substrates, providing the possibility for very inexpensive, highly functional electronic paper. The broader impacts of the planning visit supported through this award are substantial. The development of a new field of electronics based upon cellulose is potentially transformative, and the complementary research expertise and infrastructure will foster strong international collaborations. Student researchers will participate in the planning visit to Portugal and gain valuable international experience and networks. Anticipated follow-on activities also include the development of long-term exchange programs for both US and Portuguese students.
