The intentional introduction of guest species into materials to modify their physical properties has long been a topic of extensive research, with doping in semiconductors being a well-known example. The emergence of two-dimensional (2D) materials with a layered structure and atomically thin nature has opened new possibilities for guest species in two distinct interactions: gating and intercalation. These methods allow for reversible modulation of 2D materials without disrupting covalent bonds. In this talk, I will discuss the relationship between 2D materials and guest species, as well as their potential applications in the fields of quantum and energy. Specifically, I will present two examples in the areas of magnetism and energy storage.
Dr. Yecun Wu is a postdoctoral scholar in the physics department at Stanford University, working with Prof. Steven Chu. His research interests encompass a range of interdisciplinary fields, including quantum sensing, quantum materials, energy storage, and sustainability. Dr. Wu's current research aims to tackle the pressing issues and challenges in the energy field by utilizing quantum technology. He received his Ph.D. in Electrical Engineering from Stanford University, where he worked with Prof. Yi Cui. During his doctoral studies, he developed innovative methods to control the properties of two-dimensional materials using guest species, which opened new avenues for their use in quantum and energy applications.
