Abstract
Weyl semimetal MoTe2 single crystal was grown by the chemical vapor transport method. Electrical resistivity, magnetoresistivity, and Hall effect in MoTe2 were studied in detail. It was shown that both the electrical resistivity in the absence of a magnetic field and the conductivity in the field depend on temperature according to a quadratic law in a wide temperature range. It has been suggested that the quadratic temperature dependence of the conductivity in a magnetic field at low temperatures might be associated with the “electron-phonon-surface” interference scattering mechanism. The analysis of data on the Hall effect in MoTe2 was carried out using single-band and two-band models. Apparently, the two-band model is preferable in such systems containing different groups of current carriers.
