The structures are observed during polarization switching in noncontact and contact mode. They are due to piezoelectric and electrostrictive indentations, respectively. Volume holographic recording has been visualized on a planes by AFM via surface corrugation. It is due to light-induced charge-density waves along the polar c axis and nondiagonal piezoelectric coupling. |
