Reversible Engineering of Topological Insulator Surface State Conductivity through Optical Excitation
Faji Xie, Zhen Lian, Shuai Zhang +13
Despite the broadband response, limited optical absorption at a particular wavelength hinders the development of optoelectronics based on Dirac fermions. Heterostructures of graphe…
Phase transition and anomalous scaling in the quantum Hall transport of topological insulator Sn-Bi1.1Sb0.9Te2S devices
Faji Xie, Shuai Zhang, Qianqian Liu +12
The scaling physics of quantum Hall transport in optimized topological insulators with a plateau precision of ~1/1000 e2/h is considered. Two exponential scaling regimes are observ…
Evidence for a Dirac nodal-line semimetal in SrAs
Shichao Li, Zhaopeng Guo, Dongzhi Fu +11
Dirac nodal-line semimetals with the linear bands crossing along a line or loop, represent a new topological state of matter. Here, by carrying out magnetotransport measurements an…
Oscillating planar Hall response from the surface electrons in bulk crystal Sn doped Bi1.1Sb0.9Te2S
Bin Wu, Xing-Chen Pan, Wenkai Wu +7
We report the low-temperature magneto-transport in the bulk-insulating single crystal of topological insulator Sn doped Bi1.1Sb0.9Te2S. The Shubnikov-de Haas oscillations appear wi…
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…
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…
