Description


This book contains all the necessary knowledge to enable a complete understanding of how piezoelectric and ferroelectric thin films work, providing the key to integrating them into Microsystems. Topics covered include: deposition methods, contamination, key processes, and characterization. The basic concepts are detailed within a framework of thermodynamics: ferro-para phase transition, strain-stress relations, dielectric formalism, piezoelectricity, electrostriction and acoustics. An extended part of this book is dedicated to state-of-the-art applications in all fields of microsystems.

A major aspect is the approach it takes to the topic: it starts with complete descriptions of piezo- and ferro-films from basic concepts, in each case maintaining two different perspectives: on the one hand, microscopic models, and on the other hand, thermodynamics.

A chapter is dedicated to electrostrictive thin films, with a special focus on tunable resonators - an area as yet unpublished in book form. The exhaustive material in this book certainly makes it one of the most complete works on this topic, especially concerning acoustic resonators.
