"description": "A comprehensive study of the electronic and structural phase transition from 1T` to T<sub>d</sub> in the bulk Weyl semimetal Mo<sub>1-x</sub>W<sub>x</sub>Te<sub>2</sub> at different doping concentrations has been carried out using time-of-flight momentum microscopy (including circular and linear dichroism), X-ray photoelectron spectroscopy, X-ray photoelectron diffraction, X-ray diffraction (XRD), angle-resolved Raman spectroscopy, transport measurements (including longitudinal elastoresistance), density functional theory (DFT) and Kikuchi pattern calculations. High-resolution, angle-resolved photoemission spectroscopy at 20 K reveals surface electronic states, which are indicative for topological Fermi arcs. Their dispersion agrees with the position of Weyl points predicted by DFT calculations based on the precise crystal structure of our samples obtained from XRD measurements. Raman spectroscopy confirms the inversion symmetry breaking for the T<sub>d</sub>-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 T<sub>d</sub> from 230 K to 270 K. Magnetoresistance and longitudinal elastoresistance show significantly increased values in the T<sub>d</sub>-phase.\nThis dataset contains the raw data discussed in the manuscript with the same title.",
