目的：该计划的目标是将石墨烯与硅集成电路进行异质集成，以实现下一代纳米电子学，利用成熟硅系统的复杂性、规模、成本和技术扩散，并将石墨烯的独特功能用于未来无处不在的先进系统。其智力价值是开创了一项新的跨学科研究，首次为先进系统创建与硅电子集成的石墨烯器件。这些系统将提供可调功能和更高的计算效率，超越独立硅技术的性能。这项工作分为五个基本任务，这些任务是克服现有挑战所必需的，包括晶圆级增长，具有最小非理想性的优化器件，以及石墨烯-硅太赫兹电子器件的首次实现。更广泛的影响：更广泛的影响是未来新的先进石墨烯-硅集成系统的扩散，以造福更广泛的社会。这种系统是变革性的，因为石墨烯的集成将低成本无处不在的硅技术的能力扩展到太赫兹领域，增加了可调谐性，导致革命性的新产品，就像千兆赫硅电子革命性的移动的通信一样。 示例系统包括：用于成像、安全、通信和光谱学的太赫兹收发器;用于电子鼻应用的传感器阵列;以及石墨烯启用的光电子学。此外，研究计划和教育推广计划之间的紧密耦合将在纳米电子学的最前沿提供本科生研究经验，并为中学生提供接触纳米科学的机会。这些推广活动将影响代表性不足的学生，并激励他们追求技术职业。

Objective: The objective of this program is the heterogeneous integration of graphene with silicon integrated circuits for next generation nanoelectronics that leverage the complexity, scale, cost, and technology proliferation of mature silicon systems with the unique functionalities of graphene for future ubiquitous advanced systems.Intellectual Merit: The intellectual merit is the pioneering of a new cross-disciplinary research to create graphene devices integrated with silicon electronics for advanced systems for the first time. These systems will offer tunable functionality and greater computational efficiency beyond the performance of stand-alone silicon technology. The effort is organized into five essential tasks which are necessary to overcome the existing challenges ranging from wafer-scale growth, optimized devices with minimal non-idealities, and the first realization of graphene-silicon terahertz electronics.Broader Impacts: The broader impacts are the future proliferation of new advanced graphene-silicon integrated systems for the benefit of the broader society. Such systems are transformative because the integration of graphene extends the capabilities of low-cost ubiquitous silicon technology into the terahertz regime with added tunability leading to revolutionary new products much like gigahertz silicon electronics revolutionized mobile communications. Example systems include: terahertz transceivers for imaging, security, communication and spectroscopy; sensor arrays for electronic-nose applications; and graphene enabled optoelectronics. In addition, tight coupling between the research program and educational outreach initiatives will provide undergraduate research experiences at the forefront of nanoelectronics, and also afford secondary school students exposure to nanoscience. The outreach initiatives will impact scores of underrepresented students and inspire them to pursue technical careers.
