Popis: | We report the crystalline quality and electrical properties of PbZr1-x TixO3 (PZT) films on Si substrates with epitaxially grown CeO2 buffer layers. CeO2 buffer layers were deposited by the electron-beam-assisted evaporation technique, and PZT films were formed by the sol-gel technique. It is shown that CeO2 buffer layers, which were epitaxially grown on Si(111) substrates at 500°C, effectively suppressed Si and Pb interdiffusion between PZT films and Si substrates. Furthermore, the capacitance-voltage and current-voltage properties of PZT/CeO2/Si indicated a ferroelectric nature and excellent breakdown strength. |
