A analysis crew led by Professor Leo Tianshuo Zhao from the Division of Electrical and Digital Engineering on the School of Engineering, College of Hong Kong (HKU), has developed the world’s smallest totally printed infrared photodetectors, that are an progressive room-temperature nano-printing platform that overcomes the restrictions of conventional silicon-based know-how.
Close to-infrared (NIR) know-how is important for purposes reminiscent of autonomous techniques, biomedical sensing, and high-speed optical communications. Nevertheless, standard silicon-based CMOS know-how can not straight detect NIR wavelengths. Present options depend on costly processes to develop IR-absorbing supplies and bond them to silicon circuits, including complexity and limiting sensor miniaturisation.
To deal with this problem, Professor Zhao’s analysis crew has developed a nano-printing platform to reveal the world’s smallest totally printed infrared photodetectors—marking a big development in optoelectronic system fabrication.
