REU SITE: Collaborative Research: Nanoscale Detectives -- Elucidating the Structure and Dynamics of Hybrid Perovskite Systems

目前正在设计包含有机和无机成分的混合材料，以创造具有纳米级组成和形态控制特性的新材料。面向本科生的研究三角研究体验(RT-REU)将利用在混合材料，特别是混合钙钛矿材料方面的合作研究优势，以及RTNN的集成纳米技术工具，就具有直接和有形技术应用(例如太阳能电池、照明、激光)的及时研究主题提供最先进的研究体验。该项目的本科生参与者将在北卡罗来纳大学教堂山分校、北卡罗来纳州州立大学或杜克大学经验丰富的教师导师的指导下进行新颖的研究。在招聘过程中，将把重点放在代表性不足群体的学生以及那些在本国机构进行研究机会有限的学生，目标是让75%的参与者满足这些人口统计数字。除了实验室内的研究体验外，学生活动还包括混合钙钛矿和纳米表征技术的同步和异步教学、专业发展和丰富活动、网络和社交活动，以及他们研究的口头和书面交流体验。每名REU参与者还将与在REU现场协作的不同机构的类似领域工作的另一名参与者配对。这一综合计划将加强机构间的合作，推进研究项目，并为REU参与者提供多样化的研究体验。该REU计划有三个目标：(1)提供混合钙钛矿材料的实践研究经验，以加强学生对尖端表征技术和分析工具的知识，这些技术和分析工具可用于评估混合钙钛矿系统的纳米结构；(2)培养学生在STEM领域追求职业生涯的兴趣，特别是来自代表性较低群体的学生；以及(3)发展每个参与者的沟通和网络技能。学生将接触并体验最先进的合成、建模和表征工具，这些工具应用于当代有机-无机混合材料的研究主题。学生将获得工程混合材料系统的新视角，并将直接将这些知识应用于系统设计的改进和/或新特性和应用的研究。参加该项目的学生将接触到RTNN设施中的先进工具和技术，不仅成为用户，还将把他们的知识、专业知识和联系带到他们所在的机构。该计划还将把学生连接到国家纳米技术协调基础设施(NNCI)网络中的其他站点，这将帮助学生为未来的STEM职业生涯建立一个科学网络和支持系统。该项目由工程教育和中心部(工程局)和材料研究部(数学和物理科学局)联合资助。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

Hybrid materials, incorporating both organic and inorganic components, are currently being engineered to create new materials with properties controlled by nanoscale composition and morphology. The Research Triangle Research Experience for Undergraduates (RT- REU) will leverage the strength of collaborative research on hybrid materials, specifically hybrid perovskites, together with the integrated nanotechnology tools of the RTNN to provide a state-of-the-art research experience on a timely research topic that has direct and tangible technological applications (e.g. solar cells, lighting, lasers). Undergraduate participants in this program will conduct novel research under the guidance of an experienced faculty mentor at UNC-Chapel Hill, NC State University, or Duke University. A heavy emphasis during recruiting will be placed on students from underrepresented groups as well as those who have limited opportunities to pursue research at their home institutions, aiming for 75% of participants to meet these demographics. In addition to the in-lab research experience, student activities include synchronous and asynchronous instruction in hybrid perovskites and nanoscopic characterization techniques, professional development and enrichment activities, networking and social activities, and experience with oral and written communication of their research. Each REU participant will be also paired with another participant working in a similar area at a different institution in the REU site collaboration. This integrated program will enhance inter-institutional collaboration, advance research projects, and provide a diverse research experience for REU participants.There are three objectives for this REU program: (1) To provide a hands-on research experience in hybrid perovskite materials that reinforces student knowledge of cutting-edge characterization techniques and analytical tools that can be used to evaluate the nanoscopic structure of hybrid perovskite systems; (2) to foster student interest in pursuing a career in STEM fields, especially those from underrepresented groups; and (3) to develop communication and networking skills in each of the participants. Student participants will gain exposure to and experience with state-of-the-art synthesis, modeling and characterization tools as applied to a contemporary research topic on hybrid organic-inorganic materials. Students will gain new perspectives on engineered hybrid material systems and will directly apply this knowledge to the improvement of system designs and/or the investigation of novel properties and applications. Students in the program will be exposed to advanced tools and techniques in RTNN facilities and will not only become users themselves but will also bring their knowledge, expertise, and connections to their home institutions. The proposed program will also connect students to other sites in the National Nanotechnology Coordinated Infrastructure (NNCI) network, which will help students to build a scientific network and support system for future STEM careers.This project is jointly funded by the Division of Engineering Education and Centers (Directorate for Engineering), and the Division of Materials Research (Directorate for Mathematical and Physical Sciences).This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
