CAREER: Massively Parallel and Manufacturable Self-Assembly Techniques for Interfacing and Integrating Nanowires in Devices and Circuits

该学院早期职业生涯(Career)的研究目标是解决一维半导体纳米线与器件和电路的接口和互连的长期问题，并提出开发新的可大规模制造的解决方案。该计划的广泛目标是促进我们对纳米线-块体界面的设备物理理解，并促进具有创新量子效应的基于纳米线的设备和系统的设计、集成和大规模生产的新实用技术。尽管在纳米线合成方面取得了重大进展，并展示了许多有希望的单一器件，但由于我们无法将纳米线可控地整合到集成电路中，纳米线的应用一直停滞不前。与用于器件物理研究的将电极顺序连接到单个纳米线的研究性方法不同，这项研究将使用一种新的技术，即在预制电极之间外延连接纳米线，以重复制造超高密度和低成本的器件和电路阵列。将探索生长条件、掺杂技术和晶片加工方法，以了解和优化纳米线-块体连接。该职业计划的教育目标是显著影响加州大学戴维斯分校研究生和本科生的研究经验，以及奥克兰公立学校系统中大量的少数族裔学生。该协会建议开发一门新的纳米技术课程，名为纳米结构器件：物理与技术，旨在向本科生介绍和激发他们对纳米制造和他们将面临的职业机会的兴趣。PI将开发一个项目，将纳米技术进步的知识传授到加利福尼亚州奥克兰市中心一个以贫困和社会经济影响为主的社区的一所高中。拟议的研究计划将通过开发具有革命性新能力和性能的成本效益高的大规模制造方法，将纳米线转变为可靠的技术，从而极大地影响纳米制造领域。这一结果将导致前所未有的设备密度，最终使基于纳米线的设备成为商业现实，性价比大幅提高。这将促进用于电子、光子、能量存储和转换、先进光源、传感和生物系统的器件的大规模制造。研究界还将在短期内受益于开发一种通用试验台，用于将传统微制造(自下而上)和合成纳米制造(自上而下)相结合，其中自组装纳米结构与预制微结构相匹配，以测试量子设备中的新概念。

The research objective of this Faculty Early Career (CAREER) proposes to address the long-standing issues of interfacing and interconnecting one-dimensional semiconductor nanowires with devices and circuits and proposes to develop novel mass-manufacturable solutions. The broad goals of this program are to advance our device physics understanding of nanowire-bulk interfaces and to facilitate new practical technologies for design, integration and mass production of nanowire based devices and systems with innovative quantum effects. Despite significant progress in nanowire synthesis and many promising single device demonstrations, applications of nanowires have been stalled by our inability to controllably incorporate them within integrated circuits. Unlike the research-based approach of sequentially connecting electrodes to individual nanowires for device physics studies, this research will employ a novel technique of epitaxial bridging of nanowires between pre-fabricated electrodes for reproducible fabrication of ultra-dense and low-cost device and circuit arrays. Growth conditions, doping techniques and wafer processing methods will be explored to understand and optimize nanowire-bulk connections. The educational objectives of the CAREER program are focused on significantly impacting the research experience of both graduate and undergraduate students at the University of California Davis and the large numbers of minority students in Oakland public school system. The PI proposes to develop a new nanotechnology course titled Nanostructured Devices: Physics and Technology that will serve to introduce and excite undergraduate students about nano-manufacturing and the career opportunities that will be available to them. The PI will develop a program for inseminating knowledge of the advancements in nanotechnology into a high school in a predominantly underprivileged and socio-economically impacted neighborhood of downtown Oakland, California.The proposed research plan will greatly impact the fields of Nanomanufacturing by transitioning nanowires into a reliable technology through the development of cost-effective mass-manufacturing methods with revolutionary new capabilities and performances for wide variety of applications. The outcome will lead to unprecedented device density, ultimately making the nanowire based devices a commercial reality with a major improvement in the cost/performance ratio. This will facilitate mass-manufacturing of devices for electronic, photonic, energy storage and conversion, advanced light sources, sensing, and biological systems. The research community will also benefit in the near term through the development of a universal test-bed for combining conventional microfabrication (bottom-up) and synthetic nanofabrication (top-down) where self-assembled nanostructures mate to pre-fabricated microstructures to test new concepts in quantum devices.
