Abstract
Quasi‐amorphous BaTiO3 thin films (see Figure) represent a polar ionic solid without spatial periodicity. Most probably, polarity of the quasi‐amorphous BaTiO3 is associated with directional ordering of crystal motifs formed in the steep temperature gradient and stabilized by high in‐plane mechanical stress. A remarkable characteristic of quasi‐amorphous BaTiO3 is expression of strong pyro‐ and piezoelectric effects in a low dielectric constant material.Keywords
