  • Previous work has shown that electronic and structural transitions in VO2 can be decoupled by realizing an electronic transition within a monoclinic phase. Here, the authors extend this to the rutile phase by demonstrating a photodoping-driven transition from an insulating to a metallic rutile phase.

  • Despite intensive research on the electrically driven insulator-to-metal transition, this phenomenon is not well understood. Using quasi 1D nanowires of two Mott insulators, the authors reveal the central role of defects in enabling a non-thermal doping driven insulator-to metal transition.

  • Resistive switching usually occurs by the formation of conducting filaments in the direction of current flow. Here the authors study an intriguing type of volatile metal-to-insulator resistive switching in (La,Sr)MnO3, which occurs by the formation of an insulating barrier perpendicular to the current.

  • Mott materials feature scale-less relaxation dynamics after the insulator-to-metal transition that make its electric triggering dependent on recent switching events.
