A Cornell-led collaboration has created a model simulator from overlapping ultrathin monolayers and have used it to map a longstanding conundrum in physics. Read more about Model simulator helps researchers map complex physics phenomena
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.
