The investigation of nanosized ferroelectric films and ferroelectric nanocrystals has attracted much attention during the past 15 20 years. There is interest in the fundamental and applied aspects. The theoretical basis is connected with the development of the Landau-Ginzburg-Devonshire (LGD) mean field and the first principles theories to the ultrathin ferroelectric films with thickness in the vicinity of critical size. Important potential applications are possible nanosize ferroelectric films in non-volatile memories, microelectronics, sensors, pyroelectric and electro-optic devices. This new area of research of ferroelectricity is still in impetuous development and far from completion. Many topics elucidated need generalization. The book contains theory and experimental data for a wide range of ferroelectric materials.
This book examines a wide range of ferroelectric materials. It explains the theoretical background of ultrathin ferroelectric films, presents applications of ferroelectric materials, and displays the mechanism of switching of nanosized ferroelectric films.
