An epitaxial route to strain Strain can have a dramatic effect on the properties of materials. Zhang et al. introduced large in material PbTiO 3 by growing it epitaxially composite with PbO. On boundaries between two materials, their normally different lattice constants were matched, giving rise strain. As consequence, films exhibited very electric polarization even absence an field.
