There is a high demand for miniaturized, low-power gas sensors that can be widely deployed in wireless applications for improved environmental protection, for public health, and for safe and efficient operation of many industrial processes. This proposal seeks to develop such sensors for the sensitive and selective detection of greenhouse gases, such as methane and carbon dioxide at ambient temperatures. Due to their relatively inert nature, greenhouse gases are extremely hard to detect at room temperature and hence at low power. More specifically, a transistor-based device will be developed employing a new class of porous material systems called metal-organic-frameworks. These novel chemicals will be engineered to bind selectively to the target gases. The broader impact of this work lies in its impact on other scientific fields, on society and in its educational and outreach activities. More broadly, insights will impact many disciplines and technologies using MOFs, such as gas separation and CO2 sequestration; proposed device designs have the potential to disrupt many sensing applications, such as workplace safety and air quality monitoring. Additional significant impact is on human resource development. The project will provide core training for graduate and undergraduate students who will benefit from interdisciplinary training at the crossroads of electrical engineering, surface chemistry, and materials science.This proposal is centered on a new device architecture based on chemically gated field effect transistors, which can operate at room temperature, are compatible with integrated-circuit fabrication techniques, and can be rendered extremely selective by suitable functionalization of the chemically sensitive gate. Metal organic frameworks (MOFs) have been identified as the functional element for their demonstrated extreme selectivity to gaseous species. In particular, this proposal aims to demonstrate ultra-low power, chip-scale gas sensing of greenhouse gases. The intellectual merit of the proposed work lies both in the novel design architectures and in the selection of new materials for the dielectric and the chemically sensitive layers. From a fundamental point of view, the proposed research will allow understanding and predicting the factors affecting the growth of ultrathin MOFs, to achieve their integration in an electrical microdevices, and to optimize materials and designs for enhanced chemical sensing.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

对于可以广泛部署在无线应用中的小型化、低功率气体传感器存在很高的需求，以改善环境保护、公共健康以及许多工业过程的安全和有效操作。该提案旨在开发这种传感器，用于敏感和选择性地检测温室气体，例如环境温度下的甲烷和二氧化碳。由于其相对惰性的性质，温室气体在室温下非常难以检测，因此在低功率下也是如此。 更具体地说，基于晶体管的器件将采用一类称为金属有机框架的新型多孔材料系统来开发。这些新的化学物质将被设计成选择性地与目标气体结合。这项工作的更广泛影响在于它对其他科学领域、社会以及教育和外联活动的影响。更广泛地说，这些见解将影响使用MOF的许多学科和技术，例如气体分离和CO2封存;拟议的设备设计有可能破坏许多传感应用，例如工作场所安全和空气质量监测。对人力资源开发的影响也很大。该项目将为研究生和本科生提供核心培训，他们将受益于电气工程、表面化学和材料科学交叉学科的跨学科培训。该项目的核心是基于化学门控场效应晶体管的新器件架构，该晶体管可以在室温下工作，与集成电路制造技术兼容，并且可以通过化学敏感门的适当官能化而使其具有极高的选择性。金属有机骨架（MOFs）已被确定为功能元素，其表现出的极端选择性的气体物种。特别是，该提案旨在展示温室气体的超低功耗，芯片级气体传感。所提出的工作的智力价值在于在新的设计架构，并在选择新的材料的电介质和化学敏感层。从基本的角度来看，拟议的研究将允许理解和预测的因素影响的生长的CNOMOFs，以实现其集成在一个电气微型器件，并优化材料和设计，以增强化学传感。这个奖项反映了NSF的法定使命，并已被认为是值得的支持，通过评估使用基金会的智力价值和更广泛的影响审查标准。
