Abstract:

The cation diffusion coefficients and hole conductivity data in FeO, CoO, and NiO are correlated, assuming a vacancy mechanism for cation diffusion and a hopping mechanism for hole diffusion. The cation diffusion coefficients in Fe1-xO, Co1-xO, and Ni1-xO are shown to be proportional to the concentration of vacancies x in the cation lattice with identical pre-exponential and exponential terms. The hole diffusion coefficients have the same pre-exponential term, but the activation energy depends on the bonding of the hole to the respective ion. Only one of the two holes created by the introduction of a cation vacancy takes place in the conduction process. Author
