Ferroelectricity and ferroelectric phase transition -- Thin ferroelectric films and the finite-size effect -- Ultrathin ferroelectric films -- Ferroelectric nanocrystals and nanodomains -- Switching kinetics at the nanoscale
Summary
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
