Jk. Lee et al., CHARACTERISTICS OF SRBI2TA2O9 THIN-FILMS FABRICATED BY THE RF MAGNETRON SPUTTERING TECHNIQUE, Integrated ferroelectrics, 15(1-4), 1997, pp. 115-125
SBTO thin films were successfully fabricated by r.f. magnetron sputter
ing deposition. Bismuth content exists mainly in the form of (Bi2O2)(2
+) at the surface and the elemental bismuth forms at the interface bet
ween the SBTO layer and the Pt electrode. The crystal structure of SBT
O films grown on the Pt(lll) layer were preferentially c-axis oriented
. The Pt/SBTO/Pt capacitor shows Pr-P(boolean AND)r=16.3 mu C/cm(2) a
nd Ec=50kV/cm.
