Dr Zhao Jiong graduated from Tsinghua University. Currently he is associate professor in Applied Physics Department of The Hong Kong Polytechnic University. He is the co-founder of the Atomic Electron Microscopy Centre of The Hong Kong Polytechnic University, which was established in UMF, PolyU, 2023. His main research area is low-dimensional physics especially two dimensional materials and in situ electron microscopy. He has applied and developed in situ mechanical/electrical/heating/beam environmental tests on carbon nanotubes, Si nanowires, graphene and relevant 2D materials, and experimentally obtained their atomic structures, chemistry and physical properties. The atomic structures and dynamical responses in atomic scale have been observed/revealed. These previous relevant research works have been published in renowned journals such as Science, Nature Nanotechnology, PNAS, Nature communications, Science Advances, etc, with Dr Zhao as the first/corresponding authors.
