Functional and Smart Materials describes the several crystal structure systems that are frequently observed in oxide functional materials, examining the basic modules that are the building blocks of all related structures. Z.L. Wang and Z.C. Kang link the structural evolution of each system with mixed valences of rare-earth and transitional metal elements, since this connection has proven to be fundamental to the production of new materials with unique functionality. Copiously illustrated with 337 figures, and containing FORTRAN codes for calculation of crystal structure data and electron energy-loss spectra, Functional and Smart Materials is an excellent resource for researchers in materials science, solid-state chemistry, mineralogy, electron microscopy, and solid-state physics, as well as advanced graduate students in any of these disciplines.
