Two-dimensional (2D) crystals have many unique properties as compared to their bulk counterparts due to their reduced dimensionality and symmetry. A key difference is the band structures, which lead to distinct electronic and photonic properties. Additionally, 2D crystals also have many other unique properties, including high flexibility, high surface to bulk ratio, tunable band gap, etc. These unique properties of 2D crystals open up a broad territory of applications in computing, communication, energy, and medicine.
Our research interests are (1) fundamental understanding of 2D crystals and (2) nano-scale devices based on 2D crystals. Some of our recent work are featured below:
