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…
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…
Magneto-transport and Electronic Structures of BaZnBi
Yi-Yan Wang, Peng-Jie Guo, Qiao-He Yu +3
We report the magneto-transport properties and electronic structures of BaZnBi. BaZnBi is a quasi-two-dimensional (2D) material with metallic behavior. The transverse magne…
Raman scattering study of large magnetoresistance semimetals TaAs and NbAs
Feng Jin, Xiaoli Ma, Pengjie Guo +12
We have performed polarized and temperature-dependent Raman scattering measurements on extremely large magnetoresitance compounds TaAs and NbAs. In both crystals, all the R…
Raman scattering in transition metal dichalcogenides MTe2 (M = Mo, W)
Xiaoli Ma, Pengjie Guo, Changjing Yi +10
We performed comparable polarized Raman scattering studies of MoTe2 and WTe2. By rotating crystals to tune the angle between the principal axis of the crystals and the polarization…
Magnetoresistance and Shubnikov-de Hass oscillation in YSb
Qiao-He Yu, Yi-Yan Wang, Rui Lou +5
YSb crystals are grown and the transport properties under magnetic field are measured. The resistivity exhibits metallic behavior under zero magnetic field and the low temperature…
Large linear magnetoresistance in a new Dirac material BaMnBi2
Yi-Yan Wang, Qiao-He Yu, Tian-Long Xia
We report the synthesis of high quality single crystals of BaMnBi2 and investigate the transport properties of the samples. The Hall data reveals electron-type carriers and a mobil…
Resistivity plateau and extremely large magnetoresistance in NbAs2 and TaAs2
Yi-Yan Wang, Qiao-He Yu, Tian-Long Xia
In topological insulators (TIs), metallic surface conductance saturates the insulating bulk resistance with de- creasing temperature, resulting in resistivity plateau at low temper…
