About
Baodan Liu is a leading figure in advanced optoelectronics, whose work bridges the gap between conventional photodetection and emerging neuromorphic vision. His research centers on wide-bandgap semiconductors, heterojunction engineering, and the development of multifunctional devices that can dynamically switch between distinct operational modes. Liu’s most impactful contribution is the demonstration of a single trench-bridged GaN/Ga₂O₃/GaN back-to-back double heterojunction device that achieves dual-mode conversion—acting as both a high-speed photodetector and a neuromorphic vision sensor—simply by regulating bias voltage. This breakthrough, published in 2023 and already garnering over 169 citations, overcomes the fundamental speed discrepancy that previously forced these functions onto separate chips. By unifying detection and synaptic-like processing on one platform, Liu’s work paves the way for compact, energy-efficient artificial visual systems. His achievements have been recognized with multiple awards, and his designs are now inspiring next-generation hardware for autonomous sensing and in-sensor computing. For students and researchers, Liu’s research exemplifies how clever device architecture can unlock entirely new functionalities from established materials.
