摘要/描述

Bi, La 4Ti3O12(BLT)/Pb (Zr,Ti) O3(PZT)/(Bi,La) 4Ti3O12 trilayered ferroelectric thin films were epitaxially grown by pulsed laser deposition onto (001) SrTiO3 (STO) substrates with and without SrRuO3 (SRO) bottom electrodes. From x-ray pole figures and electron-diffraction patterns, the epitaxial relationships between BLT, PZT, SRO, and STO were identified to be BLT (001) PZT (001) SRO (001) SrTiO3 (001); BLT (110) PZT (100) SRO (100) SrTiO3 (100). Cross-sectional transmission electron microscopy investigations revealed that 90
