Peculiarities of electronic transport in WTe2 single crystal

Abstract

The peculiarities of electronic transport of the WTe2 single crystal, in particular, the minimum on the temperature dependence of the resistivity in a magnetic field and quadratic field dependence of the Hall resistivity, were studied. The values of the mean free path were estimated. It is suggested that the observed quadratic field dependence of the Hall resistivity may be associated with the strong electron-surface scattering mechanism, which was previously observed in compensated metals with a closed Fermi surface, under conditions of inhomogeneous distribution of electric current over the conductor cross section.
