Spectroscopy; two-dimensional quantum materials and their heterostructures; Berry curvature effects in solids; two-dimensional superconductivity and exciton condensation; magnetism; strong correlation physics.
Our research group explores new physical phenomena in atomically thin materials and their heterostructures. We study a wide range of materials with very different properties, which include semiconductors, superconductors and magnets etc. We stack them together to form heteostructures, and make electronics and opto-mechanical devices based on this material platform. To explore new phenomena, we also develop new measurement and imaging techniques suitable for specific problems on hand. Our ultimate goal is to push the limit on what can be seen and done in this two-dimensional world.
