Among the Mo- and W-based two-dimensional (2D) transition metal dichalcogenides, MoTe2 is particularly interesting for phase-engineering applications, because it has smallest free energy difference between semiconducting 2H phase metallic 1T′ phase.

We manifest mechanisms of solid-to-solid transformation by conducting...
Materials with a quasi-one-dimensional stripy magnetic order often exhibit low crystal and symmetries, thus allowing the presence of various energy coupling terms giving rise to macroscopic interplay between spin, charge, phonon.
