Observation of Weyl fermions in a magnetic non-centrosymmetric crystal
Daniel S. Sanchez, Guoqing Chang, Ilya Belopolski +15
Characterized by the absence of inversion symmetry, non-centrosymmetric materials are of great interest because they exhibit ferroelectricity, second harmonic generation, emergent…
Robust edge photocurrent response on layered Type II Weyl semimetal WTe2
Qinsheng Wang, Jingchuan Zheng, Yuan He +16
Photo sensing and energy harvesting based on exotic properties of quantum materials and new operation principles have great potentials to break the fundamental performance limit of…
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…
Topological Weyl phase transition in MoWTe
Ilya Belopolski, Daniel S. Sanchez, Yukiaki Ishida +21
Topological phases of matter exhibit phase transitions between distinct topological classes. These phase transitions are exotic in that they do not fall within the traditional Ginz…
Atomic-scale visualization of quasiparticle interference on a type-II Weyl semimetal surface
Hao Zheng, Guang Bian, Guoqing Chang +15
We combine quasiparticle interference simulation (theory) and atomic resolution scanning tunneling spectro-microscopy (experiment) to visualize the interference patterns on a type-…
Ultrafast Relaxation Dynamics of Photoexcited Dirac Fermion in The Three Dimensional Dirac Semimetal Cadmium Arsenide
Wei Lu, Shaofeng Ge, Xuefeng Liu +7
Three dimensional (3D) Dirac semimetals which can be seen as 3D analogues of graphene have attracted enormous interests in research recently. In order to apply these ultrahigh-mobi…
