The structural phases and vibrational properties of Mo_1-xW_xTe₂ alloys.

ABSTRACT: The structural polymorphism in transition metal dichalcogenides (TMDs) provides exciting opportunities for developing advanced electronics. For example, MoTe₂ crystallizes in the 2H semiconducting phase at ambient temperature and pressure, but transitions into the 1T' semimetallic phase at high temperatures. Alloying MoTe₂ with WTe₂ reduces the energy barrier between these two phases, while also allowing access to the T _d Weyl semimetal phase. The Mo_1-x W_xTe₂ alloy system is therefore promising for developing phase change memory technology. However, achieving this goal necessitates a detailed understanding of the phase composition in the MoTe₂-WTe₂ system. We combine polarization-resol
