Diagnosing the magnetic field-tuned symmetry nature of the topological electrons by conductance fluctuations in bulk-insulating BiSbTeSe2 devices
Shuai Zhang, Faji Xie, Xing-Chen Pan +5
We extract the quantum conductance fluctuations and study its magnetic field dependence in the gate-dependent transport of the topological electrons in bulk-insulating BiSbTeSe2 de…
Approaching the Type-II Dirac Point and Concomitant Superconductivity in Pt-doping Stabilized Metastable 1T-phase IrTe2
Fucong Fei, Xiangyan Bo, Pengdong Wang +12
Topological semimetal is a topic of general interest in material science. Recently, a new kind of topological semimetal called type-II Dirac semimetal with tilted Dirac cones is di…
Universal Conductance Fluctuations of Topological Insulators
Shuai Zhang, Zhaoguo Li, Fengqi Song
As an exotic quantum condensed matter, the topological insulator (TI) is a bulk-insulating material with a Dirac-type conducting surface state. Such dissipationless transport of to…
Three-Dimensional Anisotropic Magnetoresistance in the Dirac Node-Line Material ZrSiSe
Haiyang Pan, Bingbing Tong, Jihai Yu +8
The family of materials defined as ZrSiX (X = S, Se, Te) has been established as Dirac node-line semimetals, and subsequent study is urgent to exploit the promising application of…
The study on quantum material WTe2
Xing-Chen Pan, Xuefeng Wang, Fengqi Song +1
WTe2 and its sister alloys have attracted tremendous attentions recent years due to the large non-saturating magnetoresistance and topological non-trivial properties. Herein, we br…
Stepwise quantized surface states and delayed Landau level hybridization in Co cluster-decorated BiSbTeSe2 topological insulator devices
Shuai Zhang, Li Pi, Rui Wang +16
In three-dimensional topological insulators (TIs), the nontrivial topology in their electronic bands casts a gapless state on their solid surfaces, using which dissipationless TI e…
The Synthesis and Electrical Transport of Ligand-Protected Au13 Clusters
Zhongxia Wei, Wanrun Jiang, Zhanbin Bai +3
The ligand-protected Au13 clusters have been synthesized by using meso-2,3-imercaptosuccinic acid as the reducing and stabilizing agent. Transmission electron microscopic analysis…
