van der waals stacking induced topological phase transition in layered ternary transition Metal Chalcogenides
Nano Letters, 2017Co-Authors: Junwei Liu, Hua Wang, Chen Fang, Xiaofeng QianAbstract:Novel materials with nontrivial electronic and photonic band topology are crucial for realizing novel devices with low power consumption and heat dissipation and quantum computing free of decoherence. Here, we theoretically predict a novel class of ternary transition Metal Chalcogenides that exhibit dual topological characteristics, quantum spin Hall insulators (QSHIs) in their two-dimensional (2D) monolayers and topological Weyl semiMetals in their 3D noncentrosymmetric crystals upon van der Waals (vdW) stacking. Remarkably, we find that one can create and annihilate Weyl fermions and realize the transition between Type-I and Type-II Weyl fermions by tuning vdW interlayer spacing, providing the missing physical picture of the evolution from 2D QSHIs to 3D Weyl semiMetals. Our results also show that these materials possess excellent thermodynamic stability and weak interlayer binding; some of them were synthesized two decades ago, implying their great potentials for experimental synthesis, characterizatio...

large negative magnetoresistance induced by anionic solid solutions in two dimensional spin frustrated transition Metal Chalcogenides
Physical Review Letters, 2014Co-Authors: Yuqiao Guo, Jun Dai, Jiyin Zhao, Lidong Zhang, Wei Ning, Mingliang Tian, Xiao Cheng Zeng, Yi XieAbstract:We report an anionic solid solution process that induces frustrated magnetic structures within two-dimensional transition Metal Chalcogenides, which leads to huge negative magnetoresistance effects. Ultrathin nanosheets of TiTe(2-x)I(x) solid solutions, which are a new class of inorganic two-dimensional magnetic material, exhibit negative magnetoresistance with a value of up to -85%, due to the spin-dependent scattering effects of local Ti(3+) 3d(1) moments that are antiferromagnetically coupled. Moreover, TiTe(2-x)I(x) serials show unique transport behaviors with continuous evolution from Metallic to semiconducting states. We anticipate that anionic doping will be a powerful tool for optimizing the intrinsic physical properties of two-dimensional transition Metal chalcogenide system.

Ultrathin nanosheets of ${\mathrm{TiTe}}_{2\ensuremath{-}x}{\mathrm{I}}_{x}$ solid solutions, which are a new class of inorganic two-dimensional magnetic material, exhibit negative magnetoresistance with a value of up to $\ensuremath{-}85%$, due to the spin-dependent scattering effects of local ${\mathrm{Ti}}^{3+}$ $3{d}^{1}$ moments that are antiferromagnetically coupled. Moreover, ${\mathrm{TiTe}}_{2\ensuremath{-}x}{\mathrm{I}}_{x}$ serials show unique transport behaviors with continuous evolution from Metallic to semiconducting states. We anticipate that anionic doping will be a powerful tool for optimizing the intrinsic physical properties of two-dimensional transition Metal chalcogenide system.
