The objective of this research is to develop new techniques which can reliably fabricate single electron devices within the framework of CMOS technology. The approach is to fabricate single electron devices through 1) controlled positioning of nanoparticles on Self-Assembled Monolayers (SAMs) of organic molecules, 2) nanoscale positioning of electrodes through the combination of deposition, oxidation, and spacer formation, and 3) systematic study of single electron tunneling through nanoparticles and tunneling barriers. The new fabrication techniques are based on current CMOS technology so that reliable, parallel, and practical fabrication of single electron devices, connected among themselves and also to the outside macroscopic world, will be realized.The broader impacts of this program are educational and technological. Students will receive extensive training directly by participating in the research, and an interdisciplinary course, "Current topics in nanotechnology," will provide "hands-on" laboratories, benefiting students from various disciplines. This program will also provide "hands-on" science camps in which K-12 students and teachers will have direct exposure to cutting-edge equipment and clean room facilities. Along with the educational benefits, the technological benefits to our society and our economy would be enormous. The new technology will produce ultra-sensitive sensors to detect biological and chemical materials at the molecular level, which can help protect our nation from terrorism as well as provide better diagnostic tools for diseases. Also, this new technology will produce next generation devices that operate with ultra-low power consumption with great potential for commercial, military, and space applications.

本研究的目的是开发新的技术，可以可靠地制造单电子器件的CMOS技术的框架内。 该方法是通过1）在有机分子的自组装单层（SAM）上控制纳米颗粒的定位来制造单电子器件，2）通过沉积、氧化和间隔物形成的组合来进行电极的纳米级定位，以及3）系统地研究通过纳米颗粒和隧穿势垒的单电子隧穿。 新的制造技术是基于当前的CMOS技术，使可靠的，并行的，和单电子器件的实际制造，相互连接，也到外部宏观世界，将实现。该计划的更广泛的影响是教育和技术。 学生将通过参与研究直接接受广泛的培训，跨学科课程“当前纳米技术主题”将提供“动手”实验室，使来自各个学科的学生受益。该计划还将提供“动手”科学营，其中K-12学生和教师将直接接触尖端设备和洁净室设施。 沿着教育的好处，技术对我们的社会和经济的好处将是巨大的。这项新技术将生产超灵敏传感器，在分子水平上检测生物和化学材料，这有助于保护我们的国家免受恐怖主义的侵害，并为疾病提供更好的诊断工具。 此外，这项新技术将生产出具有超低功耗的下一代设备，在商业、军事和太空应用方面具有巨大潜力。
