## Description

- description: Solid-liquid phase transitions are fundamental physical processes for
    materials, but atomically-resolved microscopy has yet to capture the full dynamics
    of such a transition. We have developed a new technique for controlling melting
    and freezing of 2D molecular layers on a graphene field-effect transistor (FET)
    that allows us to image phase transition dynamics via atomically-resolved scanning
    tunneling microscopy. This is achieved by applying electric fields to an F4TCNQ-decorated
    graphene FET that induce reversible transitions between a molecular solid and
    an ionic liquid phase in 2D. Nonequilibrium melting dynamics are visualized by
    rapidly heating the graphene surface with electrical current and imaging the resulting
    evolution toward new equilibrium states. An analytical model has been developed
    that explains the observed equilibrium mixed-state phases based on direct spectroscopic
    measurement of solid and liquid molecular energy levels. Observed non-equilibrium
    melting dynamics are consistent with Monte Carlo simulations.
