Ferroelectric Ceramics: Effect of Donor Ion Doping on Dielectric,ferroelectric and Impedance Properties Indrani Coondoo

Ferroelectric materials exhibit a wide spectrum of functional properties like switchable polarization, piezoelectricity, non-linear optical activity, pyroelectricity & non-linear dielectric behaviour, that has attracted researchers for many decades. These properties render them useful for diverse applications such as sensors, transducers/actuators, nonvolatile-memories, infrared detectors, photonic communications. This book containing 5 chapters is a culmination of studies performed on donor doped Aurivillius SrBi2Ta2O9 ferroelectric ceramic. All chapters are well referenced in appropriate topical areas. Basic concepts, synthesis & characterization methods are introduced in first two chapters. A comprehensive study on optimization of synthesis conditions is provided. Last two chapters presents detailed analysis on the effect of tungsten & europium doping on dielectric, ferroelectric & impedance properties in SrBi2Ta2O9 ceramic. This monograph constitutes a valuable resource & should contribute to the understanding of properties in donor doped ferroelectric ceramic materials. It will be very useful for scientific community including students & researchers working in this field.
