摘要：
In this work, the self-assembled BaTiO3 nanocubes based resistive switching memory capacitors are fabricated with hydrothermal and drop-coating approaches. The device exhibits excellent bipolar resistance switching characteristics with ON/OFF ratio of 58-70, better reliability and stability over various polycrystalline BaTiO3 nanostructures. It is believed that the inter cube junctions is responsible for such a switching behaviour and it can be described by the filament model. The effect of film thickness on switching ratio (ON/OFF) was also investigated in details. (C) 2013 Elsevier Inc. All rights reserved.
