abstract = {WTe2 and MoTe2 in their orthorhombic (Td) phases have
emerged as prominent candidates for type-II Weyl semimetals
due to their unique quantum transport phenomena. The
distinctive electronic structure leads to unusual electron
behavior under a magnetic field, resulting in extreme
magnetoresistance (XMR). This study addresses a critical gap
in understanding the impact of structural modulation on MR
behavior, which has important implications for optimizing
materials in quantum devices and spintronics. We
successfully synthesized miscible MoxW1–xTe2 (x = 0.1 to
0.5) single crystals and investigated their structural
evolution and transport properties. Raman and powder XRD
analyses reveal that Mo doping induced a transition from the
Td phase to an intermediate monoclinic 1T′ phase. Notably,
the x = 0.3 sample exhibits the highest stability toward the
Td phase. Transport measurements reveal a significant
reduction in MR and residual resistivity ratio (RRR),
alongside an increase in electron–hole asymmetry with
higher Mo content, attributed to the reduced crystal quality
and enhancement of impurity scattering. Enhanced structural
stabilization toward the Td phase significantly improves MR
and positively influences transport properties. These
findings offer new insights into the role of structural
tuning in the electronic properties of Weyl semimetals with
implications for spintronics and quantum materials
