Title: Growth and self-assembly of BaTiO{sub 3} nanocubes for resistive switching memory cells

In this work, the self-assembled BaTiO{sub 3} 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 BaTiO{sub 3} 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. - Graphical abstract: This work describes a novel resistive switching memory cell based on self-assembled BaTiO{sub 3} nanocubes. - Highlights: • BaTiO{sub 3} nanocubes were prepared by one step facile hydrothermal method. • Self-assembled BaTiO{sub 3} nanocubes thin films were obtained by drop-coating approach. • The BaTiO{sub 3} nanocubes show excellent resistive switching properties for memory applications.
