Journal ArticleDOI
Chemically Exfoliated VSe2 Monolayers with Room-Temperature Ferromagnetism.
Wei Yu,Jing Li,Tun Seng Herng,Zishen Wang,Xiaoxu Zhao,Xiao Chi,Wei Fu,Ibrahim Abdelwahab,Jun Zhou,Jiadong Dan,Zhongxin Chen,Zhi Chen,Zejun Li,Jiong Lu,Stephen J. Pennycook,Yuan Ping Feng,Jun Ding,Kian Ping Loh +17 more
TL;DR: Using an electrochemical exfoliation approach with organic cations as the intercalants, monolayer 1T-VSe2 flakes are successfully obtained from the bulk crystal at high yield and density functional theory (DFT) calculations show that such effect can be minimized by physisorbed oxygen molecules or covalently bound thiol molecules.
Journal ArticleDOI
Gate-Tunable In-Plane Ferroelectricity in Few-Layer SnS.
Yang Bao,Peng Song,Yanpeng Liu,Zhihui Chen,Menglong Zhu,Ibrahim Abdelwahab,Jie Su,Wei Fu,Xiao Chi,Wei Yu,Wei Liu,Xiaoxu Zhao,Qing-Hua Xu,Ming Yang,Kian Ping Loh +14 more
TL;DR: In most ferroelectric materials, polarization is destabilized in ultrathin ferroelectrics as mentioned in this paper, which holds great promise for modern miniaturized sensors, memories, and optoelectronic devices.
Journal ArticleDOI
Covalent-Organic-Framework-Based Li-CO 2 Batteries
Xing Li,Hui Wang,Zhongxin Chen,Hai-Sen Xu,Wei Yu,Cuibo Liu,Xiaowei Wang,Kun Zhang,Kun Zhang,Keyu Xie,Keyu Xie,Kian Ping Loh +11 more
TL;DR: A COF constructed from hydrazone/hydrazide-containing molecular units, which shows good CO2 sequestration properties, is reported, and the composite is found to function as highly efficient cathode in a Li-CO2 battery.
Journal ArticleDOI
