Our research group has been trying to identify new electronic materials with high mobilities or high dielectric constants with the purpose of fabricating high-performance low-power devices, as well as exploring exotic physical properties. Currently, our research interests include:
1. High-mobility & High-K 2D materials;
2. Van der Waals integration for high-performance devices;
3. New synthetic strategies for chemical vapor deposition;
4. Wafer-scale single-crystalline thin films.
