Abstract
Single-crystal layers of 0.65Pb(Mg1/3Nb2/3)O-3.0.35PbTiO(3) (PMN-35PT) were grown heteroepitaxially on {001}-BaTiO3 template crystals. A {001}-BaTiO3 crystal was embedded in a fine-grained matrix of PMN-35PT containing excess PbO and heated between 950 degrees and 1150 degreesC for 0-5 h. The initia l growth of the PMN-35PT on the (001) surface and the growth of the matrix grains both displayed a t(1/3) dependence which is characteristic of diffus ion-controlled growth. Growth was limited to similar to 100-150 mum due to the significantly reduced driving force at longer times because of matrix c oarsening and porosity evolution.
