A analysis workforce 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 absolutely printed infrared photodetectors, that are an revolutionary room-temperature nano-printing platform that overcomes the restrictions of conventional silicon-based know-how.
Close to-infrared (NIR) know-how is important for functions akin to autonomous methods, biomedical sensing, and high-speed optical communications. Nevertheless, typical silicon-based CMOS know-how can’t 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 handle this problem, Professor Zhao’s analysis workforce has developed a nano-printing platform to reveal the world’s smallest absolutely printed infrared photodetectors—marking a major development in optoelectronic machine fabrication.
