MoS2 (IMAGE) National University of Singapore Caption The sketch shows scattering in the two valleys of MoS2 close to the conduction band by spin-orbit and intervalley scattering. While the first flips the spin orientation, the second changes valley with preserved spin. Very different scattering times result in the observed transition of weak antilocalisation to weak localization as experimentally observed in the magnetoresistance as function of temperature and magnetic field (right).
