Atomic Force Microscope Observation of 90° Domain Structure in the Crystallized Grains from Amorphous PbTiO3

We used an atomic force microscope(AFM) to study the surface morphology of the crystallized samples of PbTiO3 from the amorphous state prepared by rapid quenching. The specific structure on the surface was detected. We discussed a possible relationship between such a structure and the 90° domain structure of the crystalline PbTiO3.
