Berry curvature and symmetry broken induced Hall effect in MoS2
Abstract
Inversion symmetry breaking and spin-orbit coupling lead to valley and spin Hall effect in MoS2. Because of the large valley separation in momentum space, the valley index is expected to be robust. In this paper, quantum Hall effect in MoS2 originated from Berry curvature is analyzed after review of symmetry structure and spin-orbit coupling Hamiltonian of MoS2. Finally an expression and rough calculation is given for valley and spin Hall effect.
