We are interested in the emerging two-dimensional (2D) optoelectronic materials and devices, including:
1) High-performance and smart optoelectronic devices based on 2D materials, such as infrared photodetectors, silicon/2D material integrated devices, and optoelectronic synapse devices.
2) Light-matter interaction properties in 2D materials and optical molecule sensors based on 2D materials.
3) Integration technology and interface engineering of 2D materials and van der Waals heterostructures.
