TechTalk – Exploring Diamond Membranes: From Fundamental Research to Industrial Innovation
May 21, 2026 (Thursday) 4:00pm-5:00pm
Diamond is celebrated not only as a precious gemstone but also for its exceptional physical and quantum properties—particularly when it contains atomic defects known as color centers. These defects enable diamond to exhibit unique quantum behaviors under ambient conditions, making it a promising material for cutting-edge technologies. However, large-scale production of ultrathin diamond membranes has historically been a significant challenge. In this talk, we will introduce a simple, scalable, and reliable edge–exfoliation method that utilizes common office sticky tape to produce flexible, transferable polycrystalline diamond membranes. This innovative technique facilitates the mass fabrication of large-area, sub-micrometer-thick, ultra-flat, and highly flexible diamond membranes compatible with standard manufacturing processes. The inherent flexibility of these membranes unlocks new possibilities in strain engineering, quantum sensing, and other applications that were previously difficult to realize. We will also explore their potential in semiconductors, quantum technologies, and beyond. This work paves the way for integrating diamond-based materials into next-generation devices, demonstrating the transformative potential of flexible diamond membranes.
