Diffraction contrast analysis of 90° and 180° ferroelectric domain structures of PbTiO3 thin films

Science and Technology of Advanced Materials, 2011
The ferroelectric domain structure of a PbTiO3 thin film on (100) SrTiO3 has been investigated by transmission electron microscopy (TEM). Two types of a-domain were found: one extended through the film to the surface and another comprised small a-domains

Electrical de-poling and re-poling of relaxor-PbTiO3 piezoelectric single crystals without heat treatment

Nature Communications
Re-poling of unexpected partially depoled piezoelectric materials conventionally needs to be first fully depoled through annealing above their Curie temperature to revive piezoelectric performances. Here, we investigated de-poling and re-poling of Pb(In1/
