  A comprehensive study of the electronic and structural phase transition from
1T` to Td in the bulk Weyl semimetal Mo1-xWxTe2 at different doping
concentrations has been carried out using time-of-flight momentum microscopy
(including circular and linear dichroism), X-ray photoelectron spectroscopy
(XPS), X-ray photoelectron diffraction (XPD), X-ray diffraction (XRD),
angle-resolved Raman spectroscopy, transport measurements, density functional
theory (DFT) and Kikuchi pattern calculations. High-resolution angle-resolved
photoemission spectroscopy (ARPES) at 20 K reveals surface electronic states,
which are indicative of topological Fermi arcs. Their dispersion agrees with
the position of Weyl points predicted by DFT calculations based on the
experimental crystal structure of our samples determined by XRD. Raman
spectroscopy confirms the inversion symmetry breaking for the Td -phase, which
is a necessary condition for the emergence of topological states. Transport
measurements show that increasing the doping concentration from 2 to 9% leads
to an increase in the temperature of the phase transition from 1T` to Td from
230 K to 270 K. Magnetoresistance and longitudinal elastoresistance show
significantly increased values in the Td -phase due to stimulated inter-pocket
electron backscattering. The results demonstrate the close relationship between
electronic properties and elastic deformations in MoTe2.
