This Research Experiences for Undergraduates (REU) Site, Nanoscale Detectives, offers undergraduate students an immersive research experience investigating the fundamental structure, dynamics, and properties of hybrid perovskite materials — a class of materials with transformative potential in next-generation semiconductor technologies, including solar cells, photodetectors, and advanced computing. By engaging students from various academic disciplines in cutting-edge, hands-on research across the three academic institutions in making up North Carolina’s Research Triangle Area (NC State University, UNC Chapel Hill, and Duke), the program addresses the critical national need to cultivate a highly skilled STEM workforce equipped to tackle complex challenges in materials science, semiconductors and energy security. The REU Site promotes the progress of science through discovery-focused learning, while advancing national prosperity by preparing students for graduate education and careers in high-demand STEM fields. The program also recruits and trains students from community colleges as well as first-generation college students, in support of the nation’s commitment to expanding the STEM workforce in semiconductors and other strategic areas. The Nanoscale Detectives REU Site will host cohorts of twelve undergraduate students each summer for a ten-week research program at NC State University, UNC Chapel Hill, and Duke University. Participants will work closely with faculty and
