​In recent years, our research has focused on using advanced material growth techniques such as ultra-high vacuum molecular beam epitaxy to prepare new low-dimensional materials and their heterostructures, using low-temperature scanning tunneling microscopy and other technical means to characterize their structures at the single-atom level, study their novel physical properties, and explore their potential applications. Our research interests include: two-dimensional materials and heterostructures, single-molecule devices, and two-dimensional electron gas at oxide interfaces.
