DEFECT INTERACTIONS AND RELAXATION PHENOMENA ASSOCIATED WITH ELECTRONIC MOTION IN SEMICONDUCTING CERAMICS.
Abstract
Studies of the defect structures and mass transport in alkali halides and nonstoichiometric compounds are reported. Some regular solution statistical mechanical treatments were used to quantitatively predict the pairwise interaction energies between nearest-neighbor point defects in metal-excess, nonstoichiometric compounds. The ionic conductivity of pure and doped NaF was measured over a wide range of temperature and these results were analyzed by a nonlinear least-square method to yield the usual defect parameters. Interdiffusion and defect structure measurements on NiO + CoO solid solutions were carried out at elevated temperatures with the aid of appropriate x-ray methods. The diffusion observations are rationalized on the basis of the equilibrium defect structure inferred from integrated x-ray intensity data on these oxide solid solutions. (Author)
