摘要:
利用sol-gel方法在SiO2/Si基板上制备了Ca0.4Sr0.6Bi4Ti4O15(CSBT)铁电薄膜,其中Si(100)为P型。利用XRD、SEM测试手段研究了CSBT铁电薄膜的结构与形貌,测试了Au/CSBT/SiO2/Si/Au结构的介电特性和C-V曲线。

Abstract:
Ca0.4Sr0.6Bi4Ti4O15(CSBT)were preparated on SiO2/Si substracte by sol-gel method, and Si(100) was P type. The strctural characteristic and micrographs of CSBT ferroelectric thin films were examined by XRD and SEM. The metal-ferroelectric-insulation-semiconductor-metal structure showed that the dielectric properties and capacitance-voltage hysteresis was fine.
Key words:
CSBT ferroelectric thin film; sequential layer annealing method; dominated oritation; C-V characteristics
