      abstract     = {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

                      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.},
