Barkhausen effect in the first order structural phase transition in type-II Weyl semimetal MoTe2
Chuanwu Cao, Xin Liu, Xiao Ren +7
We report the first observation of the non-magnetic Barkhausen effect in van der Waals layered crystals, specifically, between the Td and 1T' phases in type-II Weyl semimetal MoTe2…

Gate Tunable Magneto-resistance of Ultra-Thin WTe2 Devices
Xin Liu, Zhiran Zhang, Chaoyi Cai +8
In this work, the magneto-resistance (MR) of ultra-thin WTe2/BN heterostructures far away from electron-hole equilibrium is measured. The change of MR of such devices is found to b…

On the quantum spin Hall gap of monolayer 1T'-WTe2
Feipeng Zheng, Chaoyi Cai, Shaofeng Ge +12
Quantum spin Hall (QSH) materials are two-dimensional systems exhibiting insulating bulk and helical edge states simultaneously. A QSH insulator processes topologically non-trivial…
