CAREER: Graphene and Graphene Nanoribbon Optoelectronic Properties and Devices

本研究的目的是设计、制造、研究和优化新型手性纳米结构混合材料器件，用于太赫兹发射器/接收器系统和具有增加存储容量的磁存储器。该方法是用掠角沉积法制备金属手性雕刻薄膜。杂化是通过将低粘性单体填充到纳米结构孔隙中来实现的，随后的聚合将使复合材料转变为功能杂化材料。教育/推广计划包括面向中学生的纳米技术迷你课程、女学生电子辅导、新材料研究计划开发研究生课程；与瑞典林雪平大学合作开展国际学生交流。智力优势：该研究计划将为手性纳米结构混合材料的革命性新电磁器件带来突破性进展。潜在的三维非易失性磁存储介质的容量可能远远超过目前可用的存储密度，并且有源太赫兹谐振器结构可能被纳入太赫兹源和探测器中。更广泛的影响：扩展非易失性直接访问计算机内存，超越当前限制，将彻底改变数据存储管理。太赫兹设备的开发将使医疗和安全检查成为可能。通信、计算、安全和健康将立即受益于这种设备技术。女学生电子指导系统缩小了女学生和工科学生之间的明显差距，并使女学生能够致力于工程专业。即将开发的纳米技术暑期课程填补了最近在暑期学生拓展活动中发现的空白。

CAREER: Chiral Nanostructure Hybrid Materials for Applications in Terahertz Reso-nator and Magnetic Storage DevicesThe objective of this research is the design, fabrication, investigation and optimization of novel chiral nanostructure hybrid material devices for applications in Terahertz emitter/receiver systems and magnetic memories with increased storage capacity. The approach is to compose metal chiral sculptured thin films deposited by glancing angle deposition. Hybridization is ob-tained by filling low viscous monomers into nanostructures pores, and subsequent polymeriza-tion will transform the composite materials into functional hybrids. The educational/outreach program consists of a nanotechnology mini-course for middle school students, female student e-mentoring, development of a new materials research program graduate course; and international student exchange in cooperation with the University of Linkoping in Sweden.Intellectual Merit: The research plan will lead to breakthrough advances for revolutionary new electromagnetic devices from chiral nanostructure hybrids. The potential three-dimensional non-volatile magnetic storage media may reach capacities far beyond the currently available sto-rage densities, and the active Terahertz resonator structures may be incorporated in Terahertz sources and detectors.Broader Impact: Expanding non-volatile direct-access computer memory beyond current limits will revolutionize data storage management. Development of Terahertz devices will en-able medical and security screening. Communication, computing, security, and health will immediately benefit from enabling this device technology. The female student electronic mentoring system closes an identified gap between female school students and engineering students, and enables female student commitment to engineering majors. The nanotechnology summer course to be developed fulfills recently identified gaps within the summer student outreach activities.
