Measurement of Diffusion of InCl 3 in AgCl Single Crystal by Internal Friction

To study the behavior of divacancy and impurity, the diffusion process of InCl 3 doped on the surface of a AgCl single crystal was measured by the internal friction and dielectric loss. All of the In 3+ ions move to the dislocation core with a rate proportional to t 1/6 and the migration energy is 0...

Description
Summary:To study the behavior of divacancy and impurity, the diffusion process of InCl 3 doped on the surface of a AgCl single crystal was measured by the internal friction and dielectric loss. All of the In 3+ ions move to the dislocation core with a rate proportional to t 1/6 and the migration energy is 0.060 eV. The concentration in the dipole of In 3+ ion and cation vacancy rapidly becomes zero at the critical temperature 566 K. Reorientation of the dipole and ionic conductivity gives an identical migration energy of 0.33 eV. The binding energy between the vacancy and the trivalent impurity E b is 0.10 eV.
