2024 Departmental Outstanding PolyU Young Alumni Award in Scholarly Achievement

We are delighted to share that Prof. Kai ZHANG has been awarded the 2024 Outstanding PolyU Young Alumni Award in Scholarly Achievement of the Department of Applied Physics. Prof. Kai Zhang's groundbreaking research has focused on the development of novel terahertz optoelectronic devices, making significant contributions to the field. His work has centred on the preparation of wafer-scale low-dimensional narrow bandgap semiconductor materials, such as black phosphorus as well as local field tuning and heterogeneous integration of terahertz devices, resulting in the development of high-speed and high-sensitivity terahertz detectors. These innovative terahertz detectors have been applied in terahertz imaging diagnosis and tissue detection systems at Huashan Hospital, allowing the hospital to realize the characterization of various biological samples, including tumors, lesions, and Achilles tendons. In recognition of his exceptional achievements, Prof. Zhang has been honoured with numerous accolades, including the 2020 "China Semiconductor Top Ten Research Progress Nomination Award," the 2021 NR45 Young Innovators Award, and the first prize of the 2022 China Association of Inventions "Invention and Entrepreneurship Award Innovation Award." Beyond his research achievements, Prof. Zhang has been an active contributor to the academic community, publishing over 100 scientific papers, writing review articles and book chapters, and delivering numerous invited presentations at leading international conferences. He has also taken on leadership roles, including serving as the Vice Chair of the 5th International Conference on Two-Dimensional Materials and Technology as well as the Organizing Committee Member of the 5th International Conference on Optoelectronics and Microelectronics Technology and Applications. Congratulations to Prof. Zhang for his significant contributions to the community!

Shafayet Yaseen Wins Prestigious Erasmus Mundus Scholarship

It is pleased to announce that Shafayet Yaseen, a student from the Department of Applied Physics (AP) at The Hong Kong Polytechnic University, has been awarded the prestigious Erasmus Mundus Scholarship. This scholarship, which accepts only up to 100 students worldwide each year with a highly selective acceptance rate of 3-5%, is a testament to Yaseen's academic and leadership excellence. The Erasmus Mundus Scholarship is on par with the selectivity of renowned institutions such as Harvard, Stanford, MIT, and Oxford. Yaseen's passion, outstanding academic achievements and strategic submissions of two recommendation letters respectively from Prof Artur Erbe of Helmholtz Zentrum Dresden Rossendorf and a distinguished industrialist in Bangladesh played crucial roles in securing this scholarship. Throughout the application process, Yaseen demonstrated exceptional engagement and expertise, impressing the panel during a challenging interview on various complex topics ranging from Quantum Physics and Material Science to Nanotechnology, Chemistry, Thermodynamics, and Solid State Physics. Furthermore, Yaseen's leadership abilities were highlighted through their roles as the President of the International Student Association (ISA) at PolyU and the Vice President of the Hong Kong PolyU English Debate Club. These positions showcased Yaseen's inspiring and effective leadership qualities, which are highly valued by the Erasmus Mundus program. The Department of Applied Physics (AP) and PolyU played a significant role in Yaseen's achievement. Under the guidance of Dr Jiong Zhao and Professor Yuen Hong Tsang, Yaseen gained valuable research experience, contributed to multiple papers, and enhanced their data analysis skills. Yaseen's research internship at Helmholtz Zentrum Dresden Rossendorf in Germany, as well as an exchange program at Nanyang Technological University in Singapore, further exemplified their academic excellence. Currently, Yaseen is actively involved in an innovative project under the Undergraduate Research and Innovation Scheme (URIS), focusing on AI and computer vision for commercial painting applications. The Department of Applied Physics acknowledges Yaseen's significant achievements, and eagerly anticipates the continued impact of his work in the scientific community and beyond.

Research on Ferroelectricity Published by Prof. Hao's Group in Nature Communications

In November 2023, a research titled "Direct Observation of Intrinsic Room-Temperature Ferroelectricity in 2D Layered CuCrP₂S₆" was published in Nature Communications. The research was conducted by Prof. Hao's group, with Weng Fu Io, a research student from Prof. Hao's group, as the first author and Prof. Hao as the corresponding author. Nature Communications is one of the world’s top journals which covers a variety of scientific topics from physical sciences to earth and environmental sciences. Its publications include a vast number of high-quality researches with high impact factor. Prof. Hao’s research studies the robust out-of-plane ferroelectricity in two-dimensional layered CuCrP₂S₆ at room temperature down to 2.6 nm, which is a potential candidate for realizing low-dimensional multiferroicity. Throughout this study, the origin of the robust ferroelectric behaviors at atomic perspective is revealed. Article in Nature Communication: https://www.nature.com/articles/s41467-023-43097-2
