GOALI: ZnO Nanowires as Building Blocks for High Performance Transparent Electronics

这项提议的目标是在聚合物或玻璃衬底上制造高迁移率的氧化锌纳米线场效应晶体管，同时具有n型和p型工作，用于透明和灵活的电子应用。该方法是：1)在生长衬底上高温沉积制备单晶n型和p型氧化锌纳米线；2)对氧化锌纳米线中的缺陷进行系统分析，了解掺杂补偿机制；3)通过场效应晶体管表征和模拟平行排列的纳米线阵列的输运特性；4)探索在透明玻璃或塑料衬底上实现平行排列的氧化锌纳米线阵列的低温质量集成。通过亚利桑那州立大学和结构化材料工业公司的合作，我们将致力于将坚固可靠的氧化锌NW器件集成到聚合物基板上，首先是设计合成工艺以了解其固态化学组成，然后是为后续的器件集成而扩大规模。拟议活动的更广泛影响是将高流动性材料(在高温下合成)低温整合到透明衬底上。教育方面将产生深远的影响；例如，该计划将在一个具有技术重要性和未来主义的领域培训人员(包括来自亚利桑那州人数较少的少数族裔的学生)，以便他们能够在完成后将科学和工程技能应用于美国的工业和研究实验室。

The objective of this GOALI proposal is the fabrication of high mobility, ZnO nanowire field-effect transistor, with both n-type and p-type doing, on polymer or glass substrate for transparent and flexible electronics applications. The approach is to: 1) Synthesize single crystal n- and p-type ZnO nanowires during high temperature deposition on a growth substrate, 2) Perform systematic analysis of the defects in ZnO nanowires, and understand the dopant compensation mechanisms, 3) Characterize and simulate transport properties of parallel aligned nanowire arrays through field effect transistor, and 4) Explore mass integration of parallel-aligned ZnO nanowire arrays onto transparent glass or plastic substrates at low temperatures.The intellectual merit lies in the transformative concepts and approaches that will greatly increase the performance, especially device speed, of transparent electronics. Through a collaborative effort between Arizona State University and Structured Materials Industries, Inc., integration of robust and reliable ZnO NW devices onto polymer substrates will be pursued, beginning with designed synthesis process to understanding their solid state chemistry, and then scaling up for subsequent device integration. The broader impact of the proposed activity is the low temperature integration of high mobility materials (synthesized at high temperatures) onto transparent substrates. The educational aspect will have far reaching consequences; for example, the program will train personnel (including student from a rich pool of underrepresented minorities in Arizona) in a technologically important and futuristic area, so that they can apply their science and engineering skills in the US industries and research laboratories upon completion.
