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 goal of this project is to create a new generation of low-power, high on-off current ratio, fast response switches. Field effect transistor (FET) switches are ubiquitous in the semiconductor industry, yet conventional FETs are constrained by the fundamental size, power and speed limits of electrons moving through silicon channels and manipulated by electrostatic gates. This project focuses on creating transistors that bypass these limits by incorporating novel channel and gate materials, and in which exotic electronic states can be manipulated. In particular, transistors are created by integrating high-mobility two-dimensional electronic channels - such as exist in a single atomic layer of carbon, or graphene - with multifunctional (e.g., electro-mechanical, magnetic) gates. These devices are then used to investigate enhanced switching capabilities - including those possessing novel charge-accumulating and storage characteristics, the use of low-loss collective excitations as a replacement to dissipative charge transport in FETs, and the development of large fan-out switches based on these concepts. The device architecture envisioned in this project provides an adaptable and reconfigurable platform capable of meeting multiple application demands and evolving with time to provide a test-bed for next generation computing, data storage, and sensing devices. Results will be achieved by close collaborations within a multidisciplinary team of materials scientists, chemists, and physicists from three universities (Drexel University, University of Illinois at Urbana-Champaign, and University of Pennsylvania), who work together on first principles-based materials design, measurements, device fabrication and analysis.NON-TECHNICAL: The success of this project can lead to a new paradigm in future nanoelectronics with impact on many applications of technological and economic importance. Concepts developed here enable devices having multiple capabilities and re-configurability, and therefore high functional density that may be attractive for computing, data storage, sensor, and other technologies. The combination of computational approaches, materials synthesis, characterization and nano-fabrication targeted at bringing together novel materials - such as graphene and multifunctional oxides - is expected to bridge multidisciplinary areas, thus opening up exciting opportunities to discover new phenomena. The multi-faceted challenges to be tackled in this project provide ample educational and training opportunities for both undergraduate and graduate students for emerging interdisciplinary fields. Leveraging PIs' ongoing efforts and involvements in organizations promoting diversity, students from underrepresented groups are aggressively recruited with the aid of multi-campus summer research opportunities to be created through this project. The PIs are also dedicated to bringing the state-of-the-art research into the classroom, and advances made here enrich curricula of courses that the PIs teach. With the aid of extensive outreach infrastructure available across the three institutions involved, the PIs leverage results from this project to advocate nanoscience and technology to groups ranging from high school students and teachers to the general public.

该项目被授予2020年及以后的纳米电子竞赛奖，得到了国家科学基金会多个董事和部门的支持，以及半导体研究公司的纳米电子研究计划的支持。技术：该项目的目标是创造新一代低功耗、高开关电流比、快速响应开关。场效应晶体管(FET)开关在半导体行业中普遍存在，然而传统的FET受到电子通过硅沟道并由静电门操纵的基本尺寸、功率和速度限制的限制。该项目专注于通过结合新的沟道和栅极材料来创造绕过这些限制的晶体管，并且可以在其中操纵奇异的电子态。具体地说，晶体管是通过将高迁移率的二维电子通道--例如存在于碳或石墨烯的单个原子层中--与多功能(例如，机电、磁)栅极相结合而产生的。这些器件随后被用来研究增强的开关能力，包括那些具有新的电荷累积和存储特性的器件，使用低损耗集体激励来替代场效应管中的耗散电荷传输，以及基于这些概念的大型扇出开关的开发。本项目设想的设备架构提供了一个可适应和可重新配置的平台，能够满足多种应用需求，并随着时间的推移而发展，为下一代计算、数据存储和传感设备提供试验台。结果将通过来自三所大学(德雷克塞尔大学、伊利诺伊大学厄巴纳-香槟分校和宾夕法尼亚大学)的材料科学家、化学家和物理学家组成的多学科团队的密切合作而实现，他们在基于第一性原理的材料设计、测量、器件制造和分析方面共同工作。非技术性：该项目的成功可能导致未来纳米电子学的新范式，对许多具有技术和经济重要性的应用产生影响。这里开发的概念使设备能够具有多种功能和可重新配置，因此具有可能对计算、数据存储、传感器和其他技术具有吸引力的高功能密度。计算方法、材料合成、表征和纳米制造的结合旨在将新材料--如石墨烯和多功能氧化物--结合在一起，预计将架起多学科领域的桥梁，从而为发现新现象开辟令人兴奋的机会。该项目将解决的多方面挑战为本科生和研究生提供了大量的教育和培训机会，使他们能够进入新兴的跨学科领域。利用私人投资机构持续不断的努力和参与促进多样性的组织，积极从代表不足的群体中招收学生，并通过该项目创造多校园暑期研究机会。PIS还致力于将最先进的研究带入课堂，在这里取得的进展丰富了PIS教授的课程。在所涉三个机构提供的广泛外联基础设施的帮助下，私人投资机构利用这一项目的成果，向从高中生和教师到普通公众的群体宣传纳米科学和技术。
