Magnetic-field-induced nonlinear transport in HfTe5
Cheng Zhang, Jinshan Yang, Zhongbo Yan +8
The interplay of electron correlations and topological phases gives rise to various exotic phenomena including fractionalization, excitonic instability, and axionic excitation. Rec…
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…
Non-saturating Quantum Magnetization in Weyl semimetal TaAs
Cheng-Long Zhang, C. M. Wang, Zhujun Yuan +8
Detecting the spectroscopic signatures of Dirac-like quasiparticles in emergent topological materials is crucial for searching their potential applications. Magnetometry is a power…
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…
Quantum oscillation and nontrivial transport in the Dirac Semimetal Cd3As2 nanodevice
Haiyang Pan, Kang Zhang, Zhongxia Wei +9
Here we demonstrate the Shubnikov de Haas oscillation in high-quality Cd3As2 nanowires grown by a chemical vapor deposition approach. The dominant transport of topological Dirac fe…
Experimental evidence and control of the bulk-mediated intersurface coupling in topological insulator Bi2Te2Se nanoribbons
Zhaoguo Li, Ion Garate, Jian Pan +14
Nearly a decade after the discovery of topological insulators (TIs), the important task of identifying and characterizing their topological surface states through electrical transp…
Enhanced quantum coherence in graphene caused by Pd cluster deposition
Yuyuan Qin, Junhao Han, Guoping Guo +8
We report on the unexpected increase in the dephasing lengths of a graphene sheet caused by the deposition of Pd nanoclusters, as demonstrated by weak localization measurements. Th…
