Multifunctional Piezoelectric Oxide Nanostructures: Fabrication Methods, Devices and Applications reviews multifunctional piezoelectric oxides, including their growth, thin films, composite films, interfacial doping effects, energy harvesting devices, and battery-free sensors. The book bridges the connection between the theoretical and experimental aspects of piezoelectric oxides, also explaining the pathways between materials-device designs-application sectors through various state-of-the-art techniques. Other sections cover the desirable properties of piezoelectric oxides, including pyroelectric, magnetoelectric, piezoelectrochemical and electrocaloric. This book is suitable for those working in the field of materials science and engineering in academia and research and development.
