## Description

- description: Martensitic transitions in organic crystals, which are diffusionless
    structural phase transitions between polymorphs, are topics of current interest.
    These transitions proceed by fast propagation of the phase front (phase boundary)
    across the crystals and induce fascinating phenomena, such as thermosalient effect
    and superelasticity, which have potential applications in molecular devices. Revealing
    the mechanism of these transitions is of crucial importance for understanding
    the origins of these phenomena and for their device applications. To this end,
    here we observe the spatio-temporal evolution of the phase front in temperature-induced
    martensitic transition in 1,2,4,5-tetrabromobenezen (TBB) crystals. We observed
    subsonic phase front propagation across the crystals with the velocity of up to
    ~800 m/s. The analysis using a nonlinear lattice model based on Landau’s theory
    of phase transitions showed that the phase front motion is described as a propagating
    solitary wave in a non-conservative system. Our results revealed the essential
    factors governing organic martensitic transitions and novel insights into the
    transition mechanism.
