Resistive hysteresis of BaTiO3 ferroelectric thin film prepared by MOD method

摘要

An MOD-made BaTiO3 (BT) thin film was prepared for investigating the relation between its ferroelectric properties and the behavior of resistive hysteresis. For the ferroelectric 110 nm-thickness BT film, its coercive field is observed to relate quantitatively to the characteristics of resistive hysteresis, where the current on/off ratio is obtained as 1–2 orders of magnitude. We consider that the ferroelectricity in the film makes a different type of behavior in resistive hysteresis and is effective for improving the behavior.
