Semiconductor materials, devices, and systems that adapt
We develop adaptive semiconductor devices and systems by integrating functional nanomaterials, high-resolution printing, mechanical deformability, and advanced optoelectronic functions. Since 2019, our work has spanned quantum dot and perovskite displays, flexible and stretchable electronics, wearable optoelectronics, and soft robotics, with results published in Nature Nanotechnology, Nature Photonics, Nature Electronics, Science Advances, Advanced Materials, and other leading journals.
