Open AccessInterlayer quantum transport in Dirac semimetal BaGa2
The quantum limit is quite easy to achieve once the band crossing exists exactly at the Fermi level (EF) in topological semimetals. In multilayered Dirac fermion systems, the density of Dirac fermions on the zero...

Open AccessDirect observation of spin-layer locking by local Rashba effect in monolayer semiconducting PtSe2 film
The generally accepted view that spin polarization in non-magnetic solids is induced by the asymmetry of the global crystal space group has limited the search for spintronics materials mainly to non-centrosymm...

Open AccessRaman signatures of inversion symmetry breaking and structural phase transition in type-II Weyl semimetal MoTe2
Transition metal dichalcogenide MoTe2 is an important candidate for realizing the newly predicted type-II Weyl fermions, for which the breaking of the inversion symmetry is a prerequisite. Here we present direct ...
