Imaging Field‐Driven Melting of a Molecular Solid at the Atomic Scale (Adv. Mater. 39/2023)

Solid–Liquid Phase Transitions In article number 2300542, Franklin Liou, Hsin-Zon Tsai, Alex Zettl, Johannes Lischner, Michael Crommie, and co-workers use scanning tunneling microscopy to image a solid–liquid phase transition with sub-nanometer spatial resolution at the surface of graphene field-effect transistor. They electrostatic gating drive reversible transitions between quasi-1D molecular solid 2D ionic liquid phase. Transiently heating cooling device enables non-equilibrium melting dynamics be visualized.
