Gate-tunable large second-order and third-order nonlinear Hall effect in topological insulator BiSbTeSe2
Fengyi Guo, Shuai Zhang, Xiubing Li +7
The nonlinear Hall effect (NLHE) holds significant promise for next-generation electronic device applications, and it is essential to explore and engineer a strong and highly tunab…
Observation of giant nonreciprocal charge transport from quantum Hall states in a topological insulator
Chunfeng Li, Rui Wang, Shuai Zhang +10
Symmetry breaking in quantum materials is of great importance and can lead to nonreciprocal charge transport. Topological insulators provide a unique platform to study nonreciproca…
Experimental evidence on the dissipationless transport of chiral edge state of the high-field Chern insulator in MnBi2Te4 nanodevices
Zhe Ying, Shuai Zhang, Bo Chen +6
We demonstrate the dissipationless transport of the chiral edge state (CES) in the nanodevices of quantum anomalous Hall insulator candidate MnBi2Te4. The device presents a near-ze…
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…
