Abstract
The effect of the ratios of the cationic components and internal strains on the critical temperature T-c and the dielectric characteristics of BSTO fe rroelectric films grown on alpha-Al2O3 [10 (1) under bar 2] and LaAlO3 subs trates were investigated. Ion backscattering diagnostics revealed a barium deficiency in the surface layer of the films and showed that the films diff er in structural quality. (C) 1999 American Institute of Physics.
