Chiral fermion reversal in chiral crystals
Hang Li, Sheng Xu, Zhi-Cheng Rao +13
In materials chiral fermions such as Weyl fermions are characterized by nonzero chiral charges, which are singular points of Berry curvature in momentum space. Recently, new types…
Topological phase transition between distinctWeyl semimetal states in MoTe2
Anmin Zhang, Xiaoli Ma, Changle Liu +10
We present experimental evidence of an intriguing phase transition between distinct topological states in the type-II Weyl semimetal MoTe2. We observe anomalies in the Raman phonon…
Thickness-dependent in-plane polarization and structural phase transition in van der Waals Ferroelectric CuInP2S6
Jianming Deng, Yanyu Liu, Mingqiang Li +7
Van der Waals (vdW) layered materials have rather weaker interlayer bonding than the intra-layer bonding, therefore the exfoliation along the stacking direction enables the achieve…
Interlayer quantum transport in Dirac semimetal BaGa
Sheng Xu, Changhua Bao, Yi-Yan Wang +8
Quantum limit is quite easy to achieve once the band crossing exists exactly at the Fermi level () in topological semimetals. In multilayered Dirac fermion system, the density…
Quantum oscillation of thermal conductivity and violation of Weidemann-Franz law in TaAs and NbAs
X. Rao, X. Zhao, X. -Y. Wang +5
We report a study of thermal conductivity and resistivity at ultra-low temperatures and in high magnetic fields for semi-metal materials TaAs and NbAs by using single cryst…
Domain wall pinning and hard magnetic phase in Co-doped bulk single crystalline Fe3GeTe2
Cong-Kuan Tian, Cong Wang, Wei Ji +6
We report the effects of cobalt doping on the magnetic properties of two-dimensional van der Waals ferromagnet Fe3GeTe2. Single crystals of (Fe{1-x}Cox)3GeTe2 with x=0-0.78 were su…
