摘要

This study examined the properties of Schottky-type diodes composed of Pt/TiO2/Ti, where the Pt/TiO2 and TiO2/Ti junctions correspond to the blocking and ohmic contacts, respectively, as the selection device for a resistive switching cross-bar array. An extremely high forward-to-reverse current ratio of similar to 10(9) was achieved at 1 V when the TiO2 film thickness was 19 nm. TiO2 film was grown by atomic layer deposition at a substrate temperature of 250 degrees C. Conductive atomic force microscopy revealed that the forward current flew locally, which limits the maximum forward current density to <10 A cm(-2) for a large electrode (an area of similar to 60 000 mu m(2)). However, the local current measurement showed a local forward current density as high as similar to 10(5) A cm(-2). Therefore, it is expected that this type of Schottky diode effectively suppresses the sneak current without adverse interference effects in a nano-scale resistive switching cross-bar array with high block density.
