| Abstract: | The sol-gel method is ideally suitable for the preparation of ferroelectric thin films such as LiNbO3, BaTiO3, KNbO3 and PZT. The preparation and properties of polycrystalline, amorphous and single crystal films of these ferroelectric oxides
are summarized. The origin of “amorphous ferroelectricity” is discussed. Single crystal KNbO3 films have been successfully fabricated into planar waveguides and their ability to convert infrared laser into green light
demonstrated. |
