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推进我们对纳米线-体界面的器件物理理解，并促进具有创新量子效应的纳米线器件和系统的设计，集成和大规模生产的新实用技术。尽管在纳米线合成和许多有前途的单器件演示方面取得了重大进展，但由于我们无法将纳米线可控地纳入集成电路，纳米线的应用一直停滞不前。与基于研究的方法，依次连接电极到单个纳米线的设备物理研究，这项研究将采用一种新的技术，外延桥接纳米线之间的预制电极的超密集和低成本的设备和电路阵列的可重复制造。生长条件，掺杂技术和晶圆加工方法将被探索，以了解和优化单晶体-体连接。职业生涯计划的教育目标集中在显著影响研究生和本科生在加州戴维斯大学和奥克兰公立学校系统的少数民族学生的大量研究经验。PI建议开发一个新的纳米技术课程，名为纳米结构器件：物理与技术，这将有助于介绍和激发本科生对纳米制造和就业机会，将提供给他们。PI将制定一项计划，将纳米技术进步的知识灌输到奥克兰市中心一个主要受社会经济影响的贫困社区的一所高中，加州。拟议的研究计划将极大地影响纳米制造领域的过渡纳米线成为一个可靠的技术，通过开发具有成本效益的大规模，具有革命性的新能力和性能的制造方法，适用于各种应用。 其结果将导致前所未有的器件密度，最终使基于纳米线的器件成为商业现实，并在成本/性能比方面取得重大改进。这将促进电子、光子、能量存储和转换、先进光源、传感和生物系统设备的大规模制造。研究界也将在短期内受益于开发一个通用测试平台，用于结合传统的微制造（自下而上）和合成纳米纤维（自上而下），其中自组装纳米结构与预制微结构相匹配，以测试量子器件中的新概念。

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.
