AbstractThe objective of this research is to develop new electronic device architectures enabled by carbon nanotubes-semiconductor junction contacts that provide new functionality and ultimately simplify device manufacturing. Metal-semiconductor contact junctions are transcendent electronic components that pervade modern electronics. Nevertheless much remains to be understood about the transport across these contacts, particularly in the rapidly evolving realm of organic semiconductors. The University of Florida researchers have discovered that carbon nanotubes provide a unique metal for such junctions that afford a new degree of freedom permitting electronic control over the junction characteristics. The approach is to fabricate devices exploiting this degree of freedom and establish the design parameters, coupling experiment with simulation tools that optimize the devices, thus demonstrating the performance and manufacturing gains to be had.The intellectual merit of the effort lies not only in the technology to be developed but also in the understanding to be gained in the more general science of metal-semiconductor contacts. Prof. Andrew Rinzler, an experimental physicist, and Prof. Jing Guo, an electronic engineer specializing in device simulation and modeling, are uniquely suited for both development of the technology and for gaining a quantitative understanding of these novel contact junctions.Broader impacts will include:Economic benefits from accelerated insertion of inexpensive organic semiconductors into commercial devices. Webcam interviews for high school teachers and students will be conducted for early exposure of K-12 students to modern electronics technology. A web-based simulation tool on carbon nanotube heterojunction devices will be developed and deployed on the NSF sponsored nanoHUB. Minority and female students will be engaged through the Society of Women Engineers chapter and the University Minority Mentorship Program at the University of Florida

本研究的目的是开发新的电子器件架构，使碳纳米管半导体结接触，提供新的功能，并最终简化设备制造。金属-半导体接触结是现代电子产品中普遍存在的卓越电子元件。然而，关于这些接触之间的输运，特别是在快速发展的有机半导体领域，还有很多问题需要了解。佛罗里达大学的研究人员发现，碳纳米管为这种结提供了一种独特的金属，这种结提供了一种新的自由度，允许对结特性进行电子控制。该方法是利用这种自由度制造设备，并建立设计参数，耦合实验与优化设备的仿真工具，从而证明了性能和制造增益had.The智力价值的努力不仅在于要开发的技术，而且在理解中获得更一般的科学的金属-半导体接触。实验物理学家Andrew Rinzler教授和专门从事器件模拟和建模的电子工程师Jing Guo教授是唯一适合开发该技术并获得对这些新型接触结的定量了解的人。更广泛的影响包括：加速将廉价有机半导体插入商业器件的经济效益。将对高中教师和学生进行网络摄像头采访，以便K-12学生尽早接触现代电子技术。一个基于网络的碳纳米管异质结器件的模拟工具将被开发和部署在NSF赞助的nanoHUB上。少数民族和女学生将通过女工程师协会分会和佛罗里达大学的大学少数民族导师计划参与进来
