Ferroelectric barium strontium titanate (BaxSr1-xTiO3) thin films with different Ba content have been fabricated as MFM configuration using sol-gel technique. The effect of barium-to-strontium ratio on the leakage current mechanism of BaxSr1-xTiO3 thin films has been investigated. The results show that the leakage current density increases as Ba content increases, which attributed to the grain size effect. The leakage current for the tested films has been studied using log (J) vs log (E) plane, which shows three distinguished linear regions. These regions have been characterized using power law () to find that: the region at low electric fields (E < 20 KV/cm) is controlled by Ohmic conduction and the other two regions (E > 20 KV/cm) are due to space charge limited conduction, which is also confirmed via modified Langmuir-Child law. In addition, it is observed that at high electric fields region (E > 1.29×105 V/m) the films show Schottky emission (SE) and PooleFrenkel (PF) emission mechanisms.

ABSTRACTFerroelectric PZT thin films on thin RuO2 (10, 30, 50nm)/Pt hybrid bottom electrodes were successfully prepared by using a modified chemical solution deposition method. It was observed that the use of a lOnm RuO2Pt bottom electrode reduced leakage current, and gave more reliable capacitors with good microstructure compare to the use of thicker RuO2/Pt bottom electrodes. Typical P-E hysteresis behavior was observed even at an applied voltage of 3V, demonstrating greatly improved remanence and coercivity. Fatigue and breakdown characteristics, measured at 5V, showed stable behavior, and only below 13-15% degradation was observed up to 1010 cycles. Thicker RuO2 layers resulted in high leakage current density due to conducting lead ruthenate or PZT pyrochlore-ruthenate and a rosette-type microstructure.
