利用化学溶液沉积法,在Pt/Ti/SiO2/Si(100)基底上和700℃条件下分别制备了Nd和(Al,Sc)共掺杂的钛酸铋薄膜(Bi3.15,Nd0.85)(Ti3-x(Alx,scx))O12[记做BNT(AI(x),sc(x))](x=0.015,0.030,0.045,0.060),并进行了这一系列薄膜的微结构、表面形貌、铁电等特性的研究.发现当掺杂含量为x=0.030时,薄膜具有较高的剩余极化强度(2Pr=24.80/2C/cm2).讨论了相关的物理机制.

A series of Nd and ( Al, Sc ) eosubstituted bismuth titanate films of ( Bi3.15 Nd0.85 ) ( Ti3-X ( Alx, Sex) ) O12 { BNT{ AI( x} ,Sc(x) ) { x =0.015,0. 030,0. 045,0.060} have been prepared on Pt/Ti/SiO2/Si( 100) substrates at 700℃ by a chemical solution deposition technique, respectively. The structural evolution and ferroelectric properties of the as-deposited films were sys- tematically investigated as a function of ( Al, Sc ) composition x. It was found that an optimized ( Al, Sc ) content,x = 0. 030, can greatly enhance the remnant polarization ( 2Pr = 24. 80μC/cm2 ) . The relevant physical mechanisms were discussed.
