NEB: Scalable Sensing, Storage and Computation with a Rewritable Oxide Nanoelectronics Platform

该项目被授予2020年及以后的纳米电子学奖，由国家科学基金会的多个董事和部门以及半导体研究公司的纳米电子学研究计划提供支持。技术：该研究项目明确地解决了关键的科学和技术挑战，如果克服这些挑战，可能会导致传统的硅制电子产品的替代品。这种新型的纳米电子平台是基于铝酸镧和钛酸锶材料的卓越性能。这两种氧化物材料之间的界面可以使用尖锐的导电探头在绝缘和金属状态之间切换。电子电路可以在接近原子间距离(两纳米)的尺度上被“写入”和“擦除”。为了开发有用的电子设备，必须开发一种能够创建和操作大量设备的方案。这种缩放是通过使用大型探头阵列来实现的。每个探头必须能够寻址多个位置，使复杂的电路能够由设备本身在单个芯片上制造。氧化物异质结构需要生长在可制造的大型衬底上：这一点已经在硅和另一种材料上得到了证明。该研究项目解决了可重新配置的存储、计算和光学传感平台的许多核心需求，该平台可以扩展到目前硅所能实现的范围之外。跨学科研究团队以突破性技术发展所必需的各种视角直接应对这些科学和技术挑战。非技术性：该项目旨在将令人兴奋的科学成果转化为尖端信息技术。这项研究直接解决了超越摩尔定律的规模需求，并有可能创造新的高科技产业，从而在美国创造需要高级技能的新工作岗位。为了帮助解决对训练有素的工人和研究人员的需求，设计了一个新的入口式教育计划，专门针对学生在开始职业生涯时在其子学科中遇到的困难。上坡路教程是由刚毕业的研究生开发的，他们学习做研究的诀窍。研究生帮助开发基于研究的学习模块，并与更广泛的研究社区共享。威斯康星大学和匹兹堡大学都继续并扩大了他们的高中外展计划，旨在增加科学和工程学科中代表性不足群体的学生数量。

This project is awarded under the Nanoelectronics for 2020 and Beyond competition, with support by multiple Directorates and Divisions at the National Science Foundation as well as by the Nanoelectronics Research Initiative of the Semiconductor Research Corporation.TECHNICAL: The research project explicitly addresses key scientific and technological challenges that, if overcome, could lead to a possible replacement for conventional electronics made from silicon. The novel nanoelectronics platform is based upon remarkable properties of materials composed of lanthanum aluminate and strontium titanate. The interface between these two oxide materials can be switched between an insulating and a metallic state using a sharp conducting probe. Electronic circuits can be "written" and "erased" at scales approaching the distance between atoms (two nanometers). To develop useful electronics, it is imperative to develop a scheme capable of creating and manipulating large numbers of devices. This scaling is achieved through the use of large probe arrays. Each probe must be capable of addressing multiple sites, enabling complex circuits to be fabricated on a single chip, by the device itself. The oxide heterostructures need to be grown on large manufacturable substrates: this has been demonstrated with both silicon and one other material. The research project addresses many of the core requirements for a reconfigurable storage, computing, and optical sensing platform that can scale beyond what is currently possible for silicon. The interdisciplinary research team directly addresses these scientific and technological challenges with the variety of perspectives essential for the development of breakthrough technologies.NON-TECHNICAL: This project seeks to transform exciting scientific achievements into cutting-edge information technologies. The research directly addresses the need for scaling beyond Moore's law and has the potential to create new high-tech industries, thus creating new jobs in the US that require advanced skill sets. To help address the need for highly trained workers and researchers, a new OnRamp education program is designed that specifically targets difficulties that students have in their sub-discipline while beginning their careers. OnRamp tutorials are developed by beginning graduate students as they learn the ropes of doing research. Graduate students help develop research-based learning modules, which are shared with a broader research community. Both University of Wisconsin and University of Pittsburgh continue and expand their high school outreach programs aimed at increasing the numbers of students in underrepresented groups in science and engineering disciplines.
