We develop solution-processed semiconductor nanomaterials and emerging optoelectronic devices by integrating materials chemistry, surface engineering, photophysics, and device science.
Our fundamental research focuses on the design and synthesis of halide perovskites and colloidal quantum dots. We bridge these material innovations with practical applications through novel processing techniques, notably direct optical lithography. This holistic approach enables us to pioneer next-generation optoelectronic devices, including visible-to-infrared perovskite/QD LEDs, color-conversion layers, SWIR photodetectors, stretchable optoelectronics, optical communication devices, and brain-inspired optical memory systems.
Ultimately, we seek to discover new materials, mechanisms, and device concepts that redefine the future of optoelectronics and displays.

Direct Optical Patterning
It is important to selectively deposit the nanocrystal arrays onto the desired locations of thin-film devices or integrated (opto)electronic circuitry by using precise material-adapted patterning methods.
05
Stretchable Optoelectronics
Stretchable optoelectronics represents a key direction for next-generation devices, enabling electronic and photonic systems that can deform without losing functionality. By combining mechanical flexibility with stable optical performance, these systems open pathways toward wearable displays, electronic skin, and human–machine interfaces.

Optoelectronic Neuromorphic Devices
Our group is developing a new optical neuromorphic that processes image data efficiently using light and electrical signals. It uses colloidal semiconducting quantum dots and perovskite nanocrystals as a light-sensing layer, enabling on-chip learning and overcoming limitations of traditional computing.
