On 2nd December, Prof. Xin LUO from Sun Yat-sen University visited IAPME and gave a talk on “The functional 2D materials”. In the seminar, he presented the latest development of the ferroelectricity and device integration. He then reported the discovery of robust room-temperature out-of-plane ferroelectricity in the unexploited distorted 1T (d1T) phase monolayer MoTe2, which is the thinnest stable ferroelectrics with out-of-plane polarization reported so far, and the In2Se3 for 2D ferroelectricity and antiferroelectricity applications. In the third part of the talk, Prof. LUO introduced the  self-intercalation of native atoms into bilayer transition metal dichalcogenides during growth generates a class of ultrathin, covalently bonded materials, which can show novel ferromagnetic properties.

Prof. Xin Luo is currently a Professor in the School of Physics, Sun Yat-sen University (SYSU), China. He received his BS and PhD degree from SYSU in 2006 and 2011. Before joining SYSU in 2018, he has worked at the Institute of High Performance Computing (IHPC), A*STAR (2011-2013) as a scientist, National University of Singapore (2013-2017) as a research scientist and the Hong Kong Polytechnic University (2017-2018) as an independent PI. His current research interests include the design and application of low dimensional materials, including 2D layered compounds for energy, information and environment applications.
