Nanoporous Carbon Nitride: A High Efficient Filter for Seawater Desalination
Weifeng Li, Yanmei Yang, Hongcai Zhou +2
The low efficiency of commercially-used reverse osmosis (RO) membranes has been the main obstacle in seawater desalination application. Here, we report the auspicious performance,…
Prediction of Novel Stable 2D-Silicon with Fivefold Coordination
Zhenhai Wang, Mingwen Zhao, Xiang-Feng Zhou +6
Silicene, an analogue of graphene, was so far predicted to be the only two-dimensional silicon (2D-Si) with massless Dirac fermions. Here we predict a brand new 2D-Si Dirac semimet…
Tunable Topological States in Electron-Doped HTT-Pt
Xiaoming Zhang, Mingwen Zhao, Feng Liu
Driving existing materials to exhibit topologically nontrivial state is of both scientific and technological interests. Using first-principle calculations, we propose the first dem…
Phagraphene: A Low-energy Graphene Allotrope composed of 5-6-7 Carbon Rings with Distorted Dirac Cones
Zhenhai Wang, Xiang-Feng Zhou, Xiaoming Zhang +4
Using systematic evolutionary structure searching we propose a new carbon allotrope, phagraphene, standing for penta-hexa-hepta-graphene, because the structure is composed of 5-6-7…
Dumbbell Stanane: A large-gap quantum spin Hall insulator
Xin Chen, Linyang Li, Mingwen Zhao
Quantum spin Hall (QSH) effect is quite promising for applications in spintronics and quantum computations, but presently can only be achieved at ultralow temperature. Searching fo…
Stain-Induced Band Inversion and Topological Nontriviality in Antimonene
Mingwen Zhao
Antimonene is a novel two-dimensional (2D) semiconducting material of group V elements proposed in a recent literature [Zhang et al., Angew. Chem. Int. Ed. 54, 1-5 (2015)]. Using f…
