Signature of Strong Spin-Orbital Coupling in the Large Nonsaturating Magnetoresistance Material WTe2.
We report the detailed electronic structure of WTe2 by high resolution angle-resolved photoemission spectroscopy. We resolved a rather complicated Fermi surface of WTe2. Specifically, there are in total nine Fermi pockets, including one hole pocket at the Brillouin zone center Γ, and two hole pockets and two electron pockets on each side of Γ along the Γ-X direction. Remarkably, we have observe...
متن کاملNonsaturating magnetoresistance and Hall coefficient reversal in a model composite semiconductor
We calculate the transverse magnetoresistance TMR and Hall coefficient RH of a three-dimensional composite medium with both positive and negative charge carriers, using the effective-medium approximation. The composite is assumed to be composed of two types of small crystallites, in which the charge carriers are either all electrons or all holes. The conductivity tensors of the two components a...

متن کاملHydrodynamic theory of thermoelectric transport and negative magnetoresistance in Weyl semimetals.
We present a theory of thermoelectric transport in weakly disordered Weyl semimetals where the electron-electron scattering time is faster than the electron-impurity scattering time. Our hydrodynamic theory consists of relativistic fluids at each Weyl node, coupled together by perturbatively small intervalley scattering, and long-range Coulomb interactions. The conductivity matrix of our theory...
متن کاملBipolar-driven Large Magnetoresistance in Silicon
Magnetoresistance (MR) effect in non-magnetic silicon has gained a renewed interest in recent years because the effect is large and shows non-saturating (linear) magnetic field dependence, which makes it a good candidate for magnetic field sensing applications.[1-3] It is known that the presence of “static” inhomogeneities like impurities, defects, and voids in non-magnetic material generate la...
