Materials scientists, physicists, chemists, and device people offer 40 papers on recent developments in the theory of non-stoichiometry problems and fundamentally new and wide-ranging applications. The sections cover experimental methods for the determination of non-stoichiometry, phase relations and point defect equilibria, and stoichiometry control in melt and solution growth and in vapor phase epitaxy.
