Microstructure of spherulitic lead zirconate titanate thin films

The features of the microstructure of radiant spherulites in lead zirconate titanate thin films are studied using scanning electron and nonlinear optical microscopy by varying the blocks size of the perovskite structure. It is shown that as the spherulite radius (or block size) increases, the rotation angle of the growth axis increases, the rotation angle velocity changes, and the magnitude of the second optical harmonic signal changes.
