SUMMARY:Exploration on the Surface State of Co3Sn2S2
DESCRIPTION:Title\nExploration on the Surface State of Co3Sn2S2\nSpeaker\nProf. Xiang-Hua Kong (Shenzhen University, Physics)\nHost\nProf. Kai Huang (GTIIT, Chemistry)\nTime and Location\nJan. 17 2022, Monday, 2-3pm,  E510 (Education Building, 5th floor)\nAbstract\nKagome lattice materials host fertile and unusual physics, which however, are challenging to be fabricated, especially of artificially designed chemical components. In this talk, I shall show the construction of a surface kagome structure by p-d electronic hybridization on a Sn surface in Co3Sn2S2. We identified that the hexagonally appeared Sn surface explicitly exhibits a kagome-like electronic feature using density functional theory (DFT) calculations combined with experimental measurements, such as non-contact atomic force microscopy (nc-AFM) images. By substituting with other elements in the top layer, DFT calculations demonstrate custom-designed surface kagome structures with various hybridized states. These results demonstrate a novel route to artificially generate surface kagome structures.\nBiography\nProf. Xiang-Hua Kong started at Shenzhen University since May 2021 with Shenzhen overseas high-caliber personnel level B. 2016/10-2021/05, Post-Doctoral Researcher, Center for the Physics of Materials, Department of Physics, McGill University, Montreal, Canada. Her researches are engaged in the fields of computational materials science, theoretical condensed matter physics and (big) data driven science, focusing on material physics for sustainable development, novel electronic structures, Atomic Force Microscopy (AFM) & Scanning Tunneling Microscopy (STM) simulation, and single-molecule device transport. Till now, she has published 29 papers in journals such as Nature communications, Chem, Advanced Materials, Angewandte Chemie, Energy & Environmental Science and ACS Nano as well as a book chapter. According to web of science, her publications have been cited more than 3500 times so far.\n
