Behavior of Dislocation Core in AgCl Single Crystal

Abstract

To study the behavior of dislocation core in AgCl, we measured the amplitude dependence of internal friction by automated Marx's composite oscillator method and the vibrational current caused by charged dislocations, which are driven with the frequency of external force, fR=50 kHz. We obtained the association energy between vacancy and metallic impurity as EA=0.96 eV and the binding energy between dislocation and vacancy as Eb=0.66 eV combining ionic conductivity measurements.
