The objective of this program is to develop a compact, practical, novel 3-terminal approach to sensing and distinguishing emissions gases using graphene's intrinsic single molecule sensitivity. This is to be accomplished using a subthreshold Silicon Carbide Metal Semiconductor Field Effect Transistor with an active epitaxially grown graphene gate as the active transducer to provide performance advantages not possible with SiC and graphene alone. The intellectual merit lies in applying subthrehsold design principles to SiC devices, as well as to gas sensors, neither of which has been done to date. Furthermore, the modes of distinguishing between gases using a compact solid-state device will be investigated, a potentially transformative concept in the realm of gas sensing.The broader impacts of this include applications in harsh-environment sensing, emissions monitoring and low-cost gas-monitoring for homes. If successful, this will provide transformational low-cost solutions to these monitoring problems, some of which are currently un-enforceable. Finally, this effort will fund 3 professional 10-minute videos (by Co-PI & Emmy-nominated documentary maker L. Kissel) documenting the scientific process in this project for the layman, and to develop materials for recruitment of students into Science and Technology, Engineering and Math fields. This project will continue University of South Carolina's commitment to expanding diversity, by seeking to match the University demographic makeup with that of the surrounding counties, through recruitment of minority students. This project will involve at least 1 African-American PhD student.

该计划的目标是开发一种紧凑，实用，新颖的3端方法，利用石墨烯固有的单分子灵敏度来传感和区分排放气体。这将使用具有有源外延生长的石墨烯栅极的亚阈值碳化硅金属半导体场效应晶体管作为有源换能器来实现，以提供单独使用SiC和石墨烯不可能实现的性能优势。 其智力价值在于将subthrehsold设计原理应用于SiC器件以及气体传感器，迄今为止这两种方法都没有实现。此外，还将研究使用紧凑型固态器件区分气体的模式，这是气体传感领域的一个潜在变革性概念。其更广泛的影响包括恶劣环境传感，排放监测和低成本家庭气体监测的应用。如果成功，这将为这些监测问题提供变革性的低成本解决方案，其中一些目前无法执行。最后，这项努力将资助3个专业的10分钟的视频（由共同PI艾美奖提名的纪录片制作人L。Kissel）为门外汉记录该项目的科学过程，并为科学技术、工程和数学领域的学生招聘开发材料。该项目将继续南卡罗来纳州的大学的承诺，扩大多样性，通过寻求匹配大学的人口构成与周边县，通过招募少数民族学生。该项目将涉及至少1名非洲裔美国博士生。
