The objective of this research is the development of a printed optically transparent transistor technology for the realization of high-brightness, high-contrast displays at the low cost paradigms enabled by printing. The approach is the development of the device and materials technologies necessary for realizing a printed transparent electronics technology using ZnO nanoparticles, a promising printable transparent semiconductor. Initial demonstrations have already resulted in transparent transistors with performing specifications approaching those required for some display applications. Further engineering at the nanostructural level is expected to result in additional performance improvement, and development of the associated conductor and dielectric technologies will allow the realization of fully-printed ZnO TFTs. Within this work, the investigators will develop ZnO-based semiconductors and Al-doped ZnO conductors and will integrate these into a fully printed transistor process to realize all-printed transparent electronics for low-cost display applications.Intellectual MeritThis proposal is technically important since it will contribute to the development of a low-cost, flexible, flat-panel display technology. With the continued penetration of information technology into everyday life, the availability of ubiquitous display capability at low-cost is crucial. Broader impacts of this proposal include mentorship of undergraduates in research, outreach to high-school students to facilitate their retention in science and engineering, and outreach to underrepresented minority groups through recruiting activities at historically black colleges and universities, with the goal of attracting underrepresented minority students into engineering research.

这项研究的目的是开发印刷的光学透明晶体管技术，以实现高亮度，高对比度显示器，以通过打印来实现低成本范式。 方法是使用ZnO纳米颗粒（一种有希望的可打印透明的半导体）实现印刷透明电子技术所需的设备和材料技术的开发。 初始演示已经导致透明的晶体管，其执行规范接近某些显示应用程序所需的规格。 纳米结构水平的进一步工程预计将导致进一步的性能，并且相关导体和介电技术的开发将允许实现全印刷的ZnO TFT。 在这项工作中，调查人员将开发基于ZnO的半导体和AL掺杂的ZnO导体，并将其集成到完全印刷的晶体管过程中，以实现用于低成本显示应用程序的全印刷的透明电子设备。在技术上，提议在技术上很重要，因为它将有助于低调，灵活的平面，平面，平面技术的发展。 随着信息技术持续渗透到日常生活中，低成本以无处不在的显示能力的可用性至关重要。 该提案的更广泛影响包括在研究中对大学生的指导，向高中生宣讲以促进其在科学和工程学中的保留，以及通过在历史悠久的黑人学院和大学招募活动的活动，以吸引代表性不足的少数族裔学生进入工程学研究的目标。
