Vacancy Mechanism

The correlation factor for impurity diffusion in the f.c.c.-structure by means of a vacancy mechanism is calculated as a function of nine distinct vacancy-atom exchange rates.Furthermore an expression is derived for the correlation factor for diffusion of aliovalent impurities in the NaCl-structure including an electrostatic impurity-vacancy interaction.
