RIAM Member made breakthrough discovery in structure and synthesis of 2D ferroelectrics

A research team led by Prof. ZHAO Jiong, Member of the Research Institute for Advanced Manufacturing (RIAM), Associate Professor of the Department of Applied Physics of The Hong Kong Polytechnic University (PolyU), has made significant advancements in the study and synthesis of 2D van der Waals materials, particularly 2D ferroelectrics. Their work has potential applications in microelectronics, artificial intelligence, and quantum information, with promising uses in high-density memory devices and energy systems. The team successfully developed a method for large-scale synthesis of 2D ferroelectrics, such as Indium Selenide (In2Se3), using transmission electron microscopy (TEM) to achieve precise structural control.

Their research, published in Nature Nanotechnology, Nature Materials, and Science, also explores novel 2D materials and their properties, including plastic deformation and polar vortices. These discoveries could revolutionize microelectronics and lead to more efficient and flexible electronic devices. The research was supported by PolyU's Atomic Transmission Electron Microscopy Laboratory and contributions of the research team of Prof. Daniel LAU Shu Ping, Chair Professor of Nanomaterials and Head of the PolyU Department of Applied Physics; Prof. Ming YANG, Assistant Professor of the PolyU Department of Applied Physics; and Prof. LY Thuc Hue, Associate Professor of the Department of Chemistry of City University of Hong Kong.
