Theoretical study on electric-pulse-induced resistance change in perovskite Pr1-x, Cax MnO3 films
钙钛矿结构Pr1－xCaxMnO3薄膜中电脉冲诱导电阻值变化的理论研究

We developed a effective tunneling model to study the electric-pulse-induced resistive switching (EPIR) effect in PCMO films, and find that the tunneling probability of the charge transport at interfaces plays an important role in the EPIR effect. We also study the nonvolatile characteristics and the hysteretic current-voltage curve in the PCMO films, the calculated results consistent with the recent experimental data. This electric-pulse- induced resistive switching effect at room temperate has excellent potential of application.
