Multiple resistance states induced by electric pulses and reset by joule heating in the hysteresis temperature range of (V0.99Cr0.01)(2)O-3

The electric pulses induced responses of (V0.99Cr0.01)(2)O-3 in hysteresis temperature range have been investigated. We observed that multiple nonvolatile resistance states can be tuned by electric pulses due to the first-order metal to insulator phase transition, and, moreover, a reset can be realized by joule heating conveniently. Our calculations showed that the potential difference near the metal-insulator boundaries but close to the insulating side is remarkably larger, driving the resistance jumps. The multi-resistance states or the nonvolatile resistance properties excited simply by electric pulses have profound significance for the explorations of solid-state devices.

Automated summary

The electric pulses induced multiple nonvolatile resistance states in (V0.99Cr0.01)(2)O-3 due to the first-order metal to insulator phase transition, and a convenient reset can be achieved by joule heating. Calculations showed that the potential difference near the metal-insulator boundaries close to the insulating side is significantly larger, driving the resistance jumps. The multi-resistance states or the nonvolatile resistance properties excited simply by electric pulses are of great significance for the explorations of solid-state devices.
