This project exploits an innovative nanomanufacturing process, solid-state superionic stamping to realize a suite of ionically modulated active nanostructures. The convergence of this electrochemical nanoimprint technique with the nano-ionic devices with enhanced transduction and information processing using superionic conductor materials opens up new routes to economically viable, active nanostructures. Specifically the team is exploring: (a) tunable nanowire resonators/antennae for THz frequencies, which will potentially lead to a new generation of high speed opto-electronic interconnects; (b) plasmonic devices for chemically sensing sub-femtoliter analytes and (c) mechanical actuators that require dramatically lower voltages and operate with much higher strain rat es and are amenable to harsh environment. In addition, we undertake fundamental research in computational and experimental characterization of ionic transport in (solid-state) superionic conductors at nanoscale, leading to a fundamental understanding of nanostructure growth by ionic conduction and strategies to actively control and modulate it. This, along with the ability to fabricate such nanostructures, creates a whole new platform for practical design and manufacturing of future mechanical, chemical and electronic circuitry.This project also contributes to educational goals of nanomanufacturing by introducing students to advanced optics and photonics, nanoscale systems design, integration and manufacturing processes. Efforts include research opportunities to undergraduates, participation in outreach activities and programs of research centers within the college of engineering at the University of Illinois and to identify and engage underrepresented minority and female students in engineering research and education. In addition, the PIs are organizing a focused symposium on the Nanomanufacturing at the 2007 ASME MSEC meeting in Atlanta.

该项目利用创新的纳米制造工艺，固态超离子冲压来实现一套离子调制的活性纳米结构。这种电化学纳米压印技术与使用超离子导体材料增强转导和信息处理的纳米离子器件的融合，为经济上可行的活性纳米结构开辟了新途径。具体而言，该团队正在探索：（a）太赫兹频率的可调谐纳米线谐振器/天线，这将有可能导致新一代高速光电互连； (b) 用于化学传感亚飞升分析物的等离子体装置和 (c) 机械致动器，其需要极低的电压并以更高的应变率运行，并且能够适应恶劣的环境。此外，我们还开展纳米级（固态）超离子导体中离子输运的计算和实验表征方面的基础研究，从而对离子传导引起的纳米结构生长以及主动控制和调节纳米结构的策略有基本的了解。这与制造此类纳米结构的能力一起，为未来机械、化学和电子电路的实际设计和制造创建了一个全新的平台。该项目还通过向学生介绍先进的光学和光子学、纳米级系统设计、集成和制造工艺，为实现纳米制造的教育目标做出贡献。努力包括为本科生提供研究机会、参与伊利诺伊大学工程学院内的外展活动和研究中心项目，以及识别和吸引代表性不足的少数族裔和女学生参与工程研究和教育。此外，PI 正在亚特兰大举行的 2007 年 ASME MSEC 会议上组织一场关于纳米制造的专题研讨会。
