Quasi‐amorphous BaTiO 3 thin films (see Figure) represent a polar ionic solid without spatial periodicity. Most probably, polarity of the quasi‐amorphous BaTiO 3 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 BaTiO 3 is expression of strong pyro‐ and piezoelectric effects in a low dielectric constant material.
