A stable and mixed structure between tetragonal and rhombohedral-like (monoclinic) phases is predicted at a compressive misfit strain of um = -0.0382 without an energy barrier. For a tensile misfit strain of um = O.0272, another phase transition between the monoclinic and orthorhombic phases was predicted with sharply high dielectric and piezoelectric responses. © 2010 American Institute of Physics}, year = {1993}, journal = {IEEE Transactions on Information Theory}, volume = {39}, number = {3}, pages = {1049-1053}, issn = {00189448}, doi = {10.1109/18.256513}, note = {cited By 0}, language = {eng}, }
