该计划将进行的研究集中在广泛的微纳电子薄膜材料和器件上。这些材料和设备的应用包括“标准”硅基设备、嗅觉传感器、超声波换能器和微流控设备。我的研究计划的长期目标是通过将基于材料的研究应用于新设备和应用来促进微纳电子设备的最先进水平。在本提案中，该方案内有两项任务或项目正在实施。目前的硅器件正在变得越来越小，容差现在达到了原子级别。这项工作扩大了对材料和器件的物理和电学特性的理解，而材料和器件的物理和电学特性对器件性能的持续提高非常重要。最新的估计表明，到2020年，尺寸将扩大到11纳米。高性能设备将需要引入高迁移率半导体，并将绝缘体厚度调整到0.7 nm以下。这项研究直接涉及半导体行业晶体管的未来规模。这一领域的培训将使学生非常适合学术或工业(半导体相关)行业。还进行了商业制造的硅基设备的研究，其中加入了聚合物来生产“可编程”的嗅觉传感器；电子鼻。这项工作适用于许多不同的行业，包括食品和饮料(包括烈酒)、农业(筒仓腐败测试)和汽车工业(排放)。这种传感器是使用标准芯片技术制造的，因此相对便宜。可以制造包含许多不同聚合物的非常大的“百万像素”系统，使设备“可编程”。该阵列系统非常灵活，可以应用于任何需要检测挥发性气味的行业。参与这些研究的学生将在许多跨学科领域接受独特的培训，使他们在学术界或工业界非常受欢迎。

The research to be performed in this program focuses on a wide range of micro- and nano-electronic thin film materials and devices. Applications for these materials and devices include "standard" silicon based devices, olfactory sensors, ultrasonic transducers and microfluidic devices. The long range objective of my research program is to advance the state-of-the-art of micro- and nano-electrics devices through the application of materials based research to novel devices and applications. In the present proposal there are two tasks or projects within this program that are being undertaken. Current silicon devices are getting smaller and tolerances are now at the atomic level. This work expands the understanding of the physical and electronic properties of materials and devices what are so important to continued increase of device performance. The latest estimates suggest dimensions will scale to 11nm by 2020. High performance devices will require the introduction of high mobility semiconductors and the scaling of insulator thicknesses below 0.7nm. This research directly addresses the future scaling of transistors in the semiconductor industry. Training in this area will make students very desirable for academic or industrial (semiconductor-related) industries. Research is also undertaken on commercially fabricated silicon-based devices incorporating polymers to produce "programmable" olfactory sensors; an electronic nose. This work is applicable to many different industries including food and beverage (including spirits), agriculture (testing of spoilage in silos), and the automobile industry (emissions). This sensor is fabricated using a standard chip technology making it relatively inexpensive. Very large, "mega-pixel" systems can be fabricated that contain many different polymers making the device "programmable". This array system is extremely flexible and can be applied to any industry where in the sensing of volatile odors is required. Students involved in these studies will be uniquely trained in a multitude of cross-disciplinary areas making them highly desirable in academia or industry.
