    Abstract

    The monodisperse manganese oxide nanoparticles with an average diameter of 30 nm were chemically synthesized. The nanoparticles assembled as a close-packed monolayer on Pt bottom electrode by dip-coating and annealing process. The Ta/Ta2O5/MnO/Pt device was fabricated. The bipolar resistive switching behaviors could be caused by the formation and rupture of conductive filaments in the switching layers. The stable self-compliance property was demonstrated which can be attributed to the high resistance Ta/Ta2O5 interface, the Schottky barrier of Ta/Ta2O5, and the discontinuity of conduction band at Ta2O5 and MnO interface. The retention characteristics of Ta/Ta2O5/MnO/Pt device were investigated. The conduction mechanisms of Ohmic conduction, space charge limited conduction, Schottky conduction and Poole-Frenkel emission had been investigated for resistance switching mechanism.
