The applica tion of these materials in various technologies – that span from clean e nergy to quantum computing – is premised upon a deep understanding of th eir physical properties. Specifically\, the behavior that they exhibit whe n driven out of equilibrium\, by strong electric and/or optical fields\, c an be crucial to many of these applications.\n\nIn my presentation\, I sum marize some of the experiments that we have performed in recent years to i nvestigate the behavior exhibited by a variety of different nanomaterials that are driven electrically far from equilibrium. In many situations\, th is driving gives rise to fundamentally new behavior\, not associated with the material in its near-equilibrium state. Just a few such examples inclu de the emergence of robust one-dimensional transport in narrow semiconduct or channels subject to strong phonon emission [1]\; negative-mass amplific ation in the narrow conduction-band states of transition-metal trichalcoge nide nanowires [2]\; Landau-Zener tunneling across the minibands of (graph ene/h-BN) van der Waals heterostructures [3]\; and dynamic resistive-switc hing phenomena associated with charge-density wave evolution in layered tr ansition-metal dichalcogenides [4\,5]. I will provide an overview of some of these phenomena in my presentation\, focusing on the use of time-resolv ed\, transient\, electrical measurements to probe the nonequilibrium dynam ics with sub-nanosecond resolution.\n\nReferences\n\n- J.
