Dwight Viehland Zhang, Ruitao 2015-09-25T20:53:38Z 2015-09-25T20:53:38Z 10000-01-01 1999 1999 A preliminary two-dimensional cellular automaton model of defect distribution was proposed based on space charge neutrality considerations. It used only pairwise nearest-neighbor interactions and neglected the elastic effects associated with lattice distortions. Simulations demonstrated a general distribution pattern for charged defects. With increasing substituent concentration, more and larger defect clusters formed, which might be related with the formation of polar nanodomains in the modified ferroelectric BaTiO3. The influence of charged defects on field-induced AFE-FE transition was discussed in terms of elastic strain effects. Made available in DSpace on 2015-09-25T20:53:38Z (GMT).
