摘要 

550 ℃、退火20 min的条件下,采用溶胶-凝胶法分别在Pt(111)/Ti/SiO2/Si(100)衬底上制备La3+Co2+摩尔分数(xy)分别为0.050.100.150.20Bi1-xLaxFeO3(BLxFO)BiFe1-yCoyO3(BFCyO)系列薄膜,并对其进行XRD、铁电性、漏电性等测试.结果表明:La3+Co2+元素的掺杂没有改变薄膜BFO钙钛矿的晶体结构,但是明显改善了薄膜的铁电性和漏电性,尤其是当xy值分别为0.15时,薄膜Bi0.85La0.15FeO3BiFe0.85Co0.15O3均达到了最优性能.在此基础上,制备Bi0.85La0.15Fe0.85Co0.15O3(BLFCO)薄膜.结果表明:复合元素掺杂比单元素掺杂获得更为理想的效果,其中剩余极化2Pr从单元素掺杂的0.071 8 C/m2提高到复合元素掺杂的0.707 0 C/m2,漏电流密度也比单元素掺杂降低了1个数量级.

Abstract: 

Perovskite multiferroic thin films Bi1-xLaxFeO3 and BiFe1-yCoyO3 with different La3+,Co2+ molar content of x/y=0.05,0.10,0.15,0.20 have been fabricated on Pt(111)/Ti/SiO2/Si(100)substrates through Sol-Gel method and annealed at 550 for 20 minutes.XRD structural characterization and performance tests of ferroelectric P-U loop,leakage current etc.were carried out.The results showed that the doping of La3+ andCo2+did not change the crystal structure of BFO,but the doping significantly improved the ferroelectricity and leakage property of the films,especially when the  x and values were 0.15 respectively,the films Bi0.85La0.15FeO3and BiFe0.85Co0.15O3 both reached the optimal performance.On this basis,Bi0.85La0.15Fe0.85Co0.15O3 thin films were prepared.The results showed that the composite doping achieved more ideal results than the single doping,in which the residual polarization 2Pr increases from 0.071 8 C/m2 to 0.707 0 mC/m2,and the leakage current density also decreases by an order of magnitude than that of single doping.
