Harold Chong

Professor Harold Chong is a Professor of Electronic Engineering at the University of Southampton's School of Electronics and Computer Science (ECS), specializing in nanoelectronics and photonics within the Department of Electronics and Electrical Engineering. His work focuses on advancing semiconductor devices, particularly zinc oxide thin-film transistors (ZnO-TFTs), nanoelectromechanical systems (NEMS), and integrated photonic technologies for applications in sensing, healthcare, and low-power computing.

His research spans:

• Nanoelectronic device physics and fabrication
• Solution-processed semiconductor materials for flexible electronics
• Quantum device engineering and dopant spin control
• Mid-infrared photonics using germanium and silicon platforms
• Biosensor development via nanowire and oxide nanostructures

Recent publications (2023-2025) reveal a concentrated effort on optimizing zinc oxide-based devices for ion sensing and energy-efficient switching, alongside innovations in silicon photonics for infrared applications. His work consistently bridges materials science with practical electronic engineering, emphasizing scalable fabrication techniques like atomic layer deposition and solution processing to enhance device stability and performance.

Professor Chong actively supervises 12 PhD students across diverse projects including nanoelectromechanical relays, laser-induced graphene sensors, and polycrystalline silicon waveguides. His research is primarily funded by EPSRC grants such as the UKRI Centre for Doctoral Training in Machine Intelligence for Nano-electronic Devices and Systems, Capability for Wafer-Level Sub-Nanometre Scale Imaging, and the MIGRATION project for mid-infrared germanium photonics.

He is a core member of the Sustainable Electronic Technologies and Centre for Health Technologies research groups at Southampton, collaborating extensively with the Optoelectronics Research Centre (ORC) and international partners to develop next-generation electronic-photonic convergence platforms.
