Extremely large magnetoresistance and high-density Dirac-like fermions in ZrB2
Qi Wang, Peng-Jie Guo, Shanshan Sun +4
We report the detailed study on transport properties of ZrB2 single crystal, a predicted topological nodal-line semimetal. ZrB2 exhibits extremely large magnetoresistance as well a…
Experimental Observation of Dirac Nodal Links in Centrosymmetric Semimetal TiB
Zhonghao Liu, Rui Lou, Pengjie Guo +9
The topological nodal-line semimetal state, serving as a fertile ground for various topological quantum phases, where a topological insulator, Dirac semimetal, or Weyl semimetal ca…
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…
Observation of Open-Orbit Fermi Surface Topology in Extremely Large Magnetoresistance Semimetal MoAs
R. Lou, Y. F. Xu, L. -X. Zhao +14
While recent advances in band theory and sample growth have expanded the series of extremely large magnetoresistance (XMR) semimetals in transition metal dipnictides (…
Pressure-induced topological phase transition in LaSb: First-principles study
Peng-Jie Guo, Huan-Cheng Yang, Kai Liu +1
By using first-principles electronic structure calculations, we predict that the extreme magnetoresistance (XMR) material LaSb takes a topological phase transition without breaking…
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…
