An exploration of the limits of stability of the LiNb0 3 structure field with A and B site cation substitutions

Abstract
A comparative study of crystal chemistry of LiM5+03, M = Nb5+ or Ta5+ was carried out. The limits of stability of the LiNb03 structure and the Tc appear to be controlled primarily by the sizes of the substitutional ions. The LiNb03 films were grown by the liquid phase epitaxy (LPE) technique, using the Li2 0-V2 05 flux. The Na-doped LiNb03 films showed a 30% reduction in the temperature coefficient of SAW velocity.
